libguile/ChangeLog-scm
1
Wed Apr 5 14:32:51 1995 Gary Houston <ghouston@actrix.gen.nz>
2
3
* unix.c, ioext.c, posix.c, sys.c: Scheme name changes,
4
semantic cleanups, the port table, missing system calls
5
and coding cleanups from ghouston@actrix.gen.nz
6
7
Thu Mar 16 14:37:38 1995 Tom Lord <lord@x1.cygnus.com>
8
9
* guile.c: fixed the gcc-specific definition of the macro "AT(x)".
10
11
* guile.c (gscm_init_from_fn): Parameterize what init functions
12
get called (see guile_ks, below).
13
14
* guile-mini.c (guile_mini): a minimalist alternative to guile_ks.
15
16
* guile-ks.c (guile_ks): factor out the call to optional inits to
17
a separate file so you can link against libguile without getting
18
the kitchen sink.
19
20
* Ginit.scm (try-load of "ScmInit.scm"): Be robust in the absense
21
of a binding for the environment varialbe HOME. Try
22
(getpw (geteuid)) or just use "/".
23
24
25
Thu Mar 9 15:35:20 1995 Tom Lord <lord@x1.cygnus.com>
26
27
* gmain.c (main): Print additional error message if init file
28
can't be opened.
29
30
* guile.c (initialize_gscm): Report an error if the
31
init file can't be opened.
32
33
Thu Mar 23 23:22:59 1995 Aubrey Jaffer (jaffer@jacal)
34
35
* scm.texi (I/O-Extensions): Finished.
36
37
* Init.scm (scm:load): `loading' messages now indented.
38
39
Sat Mar 4 20:58:51 1995 Aubrey Jaffer (jaffer@jacal)
40
41
* scm.texi: documentation finished for "posix.c" and "unix.c".
42
43
* posix.c (scm_getgroups): added.
44
45
* posix.c (makfrom0str): According to glibc.info, some field in
46
structures like pwent may have NULL pointers. Changed makfrom0str
47
to return BOOL_F in this case.
48
49
Thu Mar 2 12:52:25 1995 Aubrey Jaffer (jaffer@jacal)
50
51
* time.c: CLKTCK set from CLOCKS_PER_SEC, if available. Metaware
52
HighC ported.
53
54
* scm.h: USE_ANSI_PROTOTYPES now controls prototypes (was
55
__STDC__). This allows an overly fussy compiler to still have
56
__STDC__.
57
58
From: dorai@ses.com (Dorai Sitaram)
59
* ioext.c (l_utime): include files fixed for __EMX__
60
61
Sun Feb 26 23:46:18 1995 Tom Lord <lord@x1.cygnus.com>
62
63
* repl.c (scm_app_wdr): Like scm_apply, but takes an error function.
64
The caller's continuation is never captured or escaped.
65
The error function is invoked as with scm_cwdr.
66
67
Sun Feb 26 21:03:04 1995 Aubrey Jaffer (jaffer@jacal)
68
69
* sys.c (gc_mark gc_sweep): tc7_ssymbol now gets GCed because it
70
gets used for non-GCed strings in scm_evalstr scm_loadstr.
71
(mkstrport cwos cwis): changed so caller's name is passed into
72
mkstrport().
73
74
* repl.c
75
(scm_eval_string scm_evalstr scm_load_string scm_loadstr): added
76
for easier C to scheme callbacks.
77
(loadport): variable added so lreadr() and flush_ws()
78
increment linum only when reading from the correct port.
79
(def_err_response): now handles ARGn for argument numbers > 5 and
80
unknown position arguments.
81
82
* dynl.c: Dynamic Linking now sets and restores *load-pathname*
83
around the init_ call.
84
85
Sat Feb 25 11:03:56 1995 Aubrey Jaffer (jaffer@jacal)
86
87
* scm.c (lsystem getenv softtype ed vms_debug): moved from scl.c.
88
(add_feature): moved from repl.c.
89
(features): init table removed (caused multiple symbols).
90
91
Fri Feb 24 23:48:03 1995 Aubrey Jaffer (jaffer@jacal)
92
93
* scm.c (scm_init_extensions COMPILED_INITS): Added so that
94
statically linked, compiled code can be initialized *after* most
95
of Init.scm has loaded.
96
97
Wed Feb 22 15:54:01 1995 Aubrey Jaffer (jaffer@jacal)
98
99
* subr.c (append): Added check for bad arguments and fixed errobj.
100
101
Sun Feb 19 01:31:59 1995 Aubrey Jaffer (jaffer@jacal)
102
103
* ioext.c (exec execp): changed so that 2nd arguments is argv[0]
104
(like posix) and renamed to execl and execlp.
105
(execv execvp): added.
106
107
Sat Feb 11 17:30:14 1995 Aubrey Jaffer (jaffer@jacal)
108
109
* ioext.c (lexec): moved from repl.c and scm.c.
110
(lexecp i_exec l_putenv): added.
111
112
* posix.c (open_pipe l_open_input_pipe l_open_output_pipe
113
prinpipe): moved from ioext.c.
114
(l_fork): added.
115
116
Fri Feb 10 10:50:03 1995 Aubrey Jaffer (jaffer@jacal)
117
118
* scl.c (num2long long2num): moved here from subr.c.
119
(num2ulong): fixed (< to >=) bug.
120
121
* unif.c (aset array2list array_ref cvref): uniform integers and
122
unsigned integer arrays now handle full size integers (and
123
inexacts) using num2long, num2ulong, long2num, and ulong2num when
124
INUMS_ONLY is not defined.
125
126
* scmfig.h (INUMS_ONLY): defined when INUMs are the only numbers.
127
128
Wed Feb 8 17:57:26 1995 Tom Lord (lord@x1.cygnus.com)
129
130
* Ginit.scm (stand-alone-repl): Use new function (rooted-repl)
131
(rooted-repl): new function
132
133
Tue Jan 31 16:46:26 1995 Tom Lord (lord@x1.cygnus.com)
134
135
* repl.c (lreadr): compare string constant names
136
in a case insensative way.
137
138
(scm_lread): Take an optional parameter CASEP.
139
If specified and not #f, then symbols are read
140
in a case sensative way.
141
142
If not specified, the state variable default_case_i is checked
143
(a C int, either 0 or 1). The state variable hasn't been
144
exposed and so is constant and depends on compile-time flags --
145
but in the future it might be made more explicit if there is a
146
need.
147
148
Sun Jan 29 23:22:40 1995 Aubrey Jaffer (jaffer@jacal)
149
150
* scm.texi (Overview): scm.1 converted to texinfo format and
151
incorporated.
152
153
Sat Jan 28 23:11:40 1995 Tom Lord (lord@x1.cygnus.com)
154
155
* repl.c (compiled-library-path): return the value of the
156
compile-time cpp macro "LIBRARY_PATH" or #f.
157
158
* Ginit.scm: use the above path to find slib on unix.
159
This solution should be generalized.
160
161
Fri Jan 27 19:58:27 1995 Tom Lord (lord@x1.cygnus.com)
162
163
* sys.c (gc_sweep): Fixed a gc bug that caused circular free-lists
164
resulting in Cells that thought they were free long after they
165
were allocated for some nefarious purpose or other.
166
167
* Makefile.in (manifest): ship all pieces of the info manual.
168
Typos fixes from ghouston.
169
170
Thu Jan 26 01:52:00 1995 Tom Lord <lord@x1.cygnus.com>
171
172
From: cessu@cs.hut.fi (Kenneth Oksanen)
173
174
* configure.in:
175
AC_CHECK_LIB(nsl, gethostent)
176
AC_CHECK_LIB(ucb, bzero)
177
AC_CHECK_LIB(socket, socket)
178
AC_CHECK_LIB(bsd, bzero)
179
180
181
From: brent@jade.ssd.csd.harris.com (Brent Benson)
182
183
* gmain.c: line 31: In ANSI C, string literals cannot span multiple
184
source lines.
185
186
* guile.c: line 592: The two cases in the ifdef are reversed, AT(X)
187
should expand to nothing if you are *not* using GNUC.
188
189
* ioext.c: line 29: On my system it is necessary to
190
include <unistd.h> *before* <sys/stat.h> in order to
191
have the correct types defined.
192
193
* ioext.c: line 194: Declaration of popen conflicts with my system's
194
popen() defined in <unistd.h>. Let the header file provide the
195
prototype!!
196
197
Sun Jan 22 11:13:58 1995 Aubrey Jaffer (jaffer@jacal)
198
199
* scm.texi (Internals): code.doc converted to texinfo format.
200
Much added and reorganized. code.doc removed.
201
202
Thu Jan 19 00:40:11 1995 Aubrey Jaffer (jaffer@jacal)
203
204
* subr.c (logbitp logtest): added.
205
206
Mon Jan 16 01:42:20 1995 Tom Lord <lord@x1.cygnus.com>
207
208
* repl.c (scm_repl): takes two arguments now (prompt and top-level).
209
Callable from Scheme.
210
211
* sys.c (scm_init_storage): only use stdin if scm_take_stdin is true.
212
Otherwise, use an empty string port. If using stdin, make it
213
unbuffered.
214
215
Sun Jan 15 21:51:37 1995 Tom Lord <lord@x1.cygnus.com>
216
217
* sys.c (scm_mkarray, scm_free_array, mark_arrays): support for
218
C programs. malloc/free style interface to allcoating
219
protected storage of type SCM*.
220
221
Sun Jan 15 17:49:43 1995 Tom Lord (lord@x1.cygnus.com)
222
223
* guile.c: new file. Friendly C interface for Guile.
224
(see file GUILE)
225
226
* repl.c (scm_cwdr): added call-with-dynamic-root (see scm.texi).
227
228
Sat Jan 14 23:35:21 1995 Tom Lord (lord@x1.cygnus.com)
229
230
* repl.c, subr.c: re-arrangement, commenting
231
of source in preparation for pulling repls apart
232
for libguile.
233
234
Wed Jan 11 14:45:17 1995 Aubrey Jaffer (jaffer@jacal)
235
236
* scl.c (num2ulong): checks for bignum sign and magnitude added.
237
238
* subr.c (logand logior logxor lognot): lognot restriction to
239
INUMs removed. Logand, logior, and logxor now will work for up to
240
32 bit signed numbers.
241
242
Tue Jan 10 13:19:52 1995 Aubrey Jaffer (jaffer@jacal)
243
244
* repl.c (def_err_response): Circuitous call to quit() replaced
245
with exit(EXIT_FAILURE);
246
(everr): Now calls def_err_response() in interrupt frame if
247
errjmp_bad or there are dynwinds to do. This prevents silent
248
failure in batch mode.
249
250
251
Mon Jan 9 00:12:14 1995 Aubrey Jaffer (jaffer@jacal)
252
253
* repl.c (handle_it): Now discards possibly used top freelist cell
254
for GC safety. Also now just punts if errjmp_bad.
255
256
* scm.texi: converted from MANUAL. GUILE documentation merged in.
257
258
Sat Jan 7 13:51:04 1995 Miles Bader (miles@eskimo.com)
259
260
* mrequire.scm: New file: Wrapper for slib require/provide that
261
makes it modular (that is, each slib package is loaded into its
262
own module, and sees only other modules that it requires).
263
264
* defmod.scm: Allow use-interface in the default module.
265
266
* libguile.scm: Put symbols common to both guile and scm
267
interfaces into the internal interface `EXTRA' (which is included
268
by both). Other random shuffling, mostly to make slib happy.
269
270
* modops.scm (extend-interface, export-interface, export): Add
271
another operation type, #f, which turns off automatic exporting of
272
the current source interface when finishing up with it. This is
273
used by export-interface to prevent trying to export all symbols.
274
275
* modops.scm (import): No longer signal an error when trying to
276
export a whole module, as we want to do this sometimes.
277
278
* Ginit.scm: No longer try to load require.scm, or depend on it;
279
In the case of getopt, we just load it manually. Also make
280
defmacro module-safe.
281
282
Sat Jan 7 01:54:11 1995 Tom Lord <lord@x1.cygnus.com>
283
284
* sys.c (scm_intern_obarray_soft): Reserve room for symbol slots.
285
286
* sys.c (scm_makstr, scm_makfromstr): added an extra parameter SLOTS.
287
The parameter means:
288
0: same as the old behavior
289
1: not useful
290
> 1: allocate SLOTS - 1 extra slots in the string storage.
291
292
The base address of SLOTS, an array of SCM, is at SLOTS(obj).
293
This is for symbol slots, and later for procedure slots.
294
If you use this in the constructor for your new type (usually
295
done by creating a string and then invoking SETLENGTH to change
296
its type), you are responsible for making sure slot contents
297
are properly gc'ed.
298
299
Callers of these were fixed as well.
300
301
Tue Jan 3 14:30:34 1995 Miles Bader (miles@eskimo.com)
302
303
* modops.scm, extlibs.scm, libguile.scm, defmod.scm: New files:
304
These implement the user-level module system.
305
306
* sys.c (scm_sym2vcell): Add another argument: definedp, which is
307
passed as additional argument to the lookup-thunk (if any).
308
If this argument is BOOL_T, this lookup is for a define (which
309
has somewhat different semantics for modules); otherwise it
310
should be satisfied with an existing variable. If the thunk
311
returns BOOL_F (meaning there was no such variable), sym2vcell
312
returns BOOL_F as well.
313
* eval.c (scm_lookupcar, scm_m_define): Use the new sym2vcell param.
314
* variable.c (scm_builtin_var): Use the new sym2vcell param.
315
316
* eval.c (scm_top_level_env): New function: return an environment
317
using the given top-level-lookup thunk.
318
* eval.c (scm_eval2): Use scm_top_level_env.
319
* eval.c (scm_eval): Use an env with a top-level lookup thunk from
320
scm_top_level_lookup_thunk_var (aka *top-level-lookup-thunk*).
321
* eval.c (scm_neval): New function: just like scm_eval, but may
322
destroy its argument. Known in scheme as eval!.
323
324
* repl.c (scm_repl, scm_tryload, lreadr): Use scm_neval, not eval_3.
325
326
* Ginit.scm (make-module): Use the new definition of top-level thunks.
327
* Ginit.scm (set-current-module): Set *top-level-lookup-thunk* too.
328
* Ginit.scm: Trash all the repl stuff; we just use the C repl now.
329
Load the user module system.
330
331
* Makefile.in: Install the user-module implementation files.
332
333
Mon Jan 2 16:27:25 1995 Miles Bader (miles@eskimo.com)
334
335
* Ginit.scm (repl:repl): Have the guile repl redefine try-load
336
instead of load, as this is the SCM primitive.
337
(module-for-each): Write module-for-each.
338
(module-search): Make this recurse into each module use-list
339
entry, as per the low-level module spec.
340
(define-macro): Make this function usable by modules that don't
341
have access to the internals of the guile module.
342
343
Sun Jan 1 22:30:25 1995 Tom Lord <lord@x1.cygnus.com>
344
345
* repl.c (scm_iprin1), subr.c (scm_lock_vector, scm_unlock_vector,
346
scm_lvector_ref, scm_lvector_set):
347
348
Added locked vectors. See N
349
350
Sat Dec 31 15:45:22 1994 Miles Bader <miles@eskimo.com>
351
352
* Ginit.scm:
353
Add define-macro, delq!.
354
355
Add a module print-function, and some new name fields
356
to the module that the modops code uses to make modules
357
print nicely (e.g., #<interface guile/module 7a89c>)
358
359
360
* eval.c(ceval): Here's a patch that makes closures & subrs
361
self-evaluating.
362
363
364
Wed Dec 28 00:31:22 1994 Tom Lord <lord@cygnus.com>
365
366
* scm.c (raise): use kill not raise, since it is more portable.
367
368
Wed Dec 21 05:18:47 1994 Tom Lord <lord@x1.cygnus.com>
369
370
* eval.c (scm_eval2): Two argument eval. The
371
second argument is #f or a proc returning a variable.
372
373
Fri Dec 9 00:40:26 1994 Tom Lord <lord@x1.cygnus.com>
374
375
* eval.c (scm_fasl_eval): eval without copying the source form.
376
This is just a temporary hack.
377
378
Sun Dec 4 21:50:37 1994 Tom Lord <lord@x1.cygnus.com>
379
380
* eval.c (scm_ceval): Added special forms LITERAL-VARIABLE-SET!
381
and LITERAL-VARIABLE-REF. The first argument of each is a
382
variable object (see variable.c). The second argument
383
of set! is an expression. They do what you'd expect.
384
-SET! returns UNSPECIFIED.
385
386
Note that one can not read a form which uses literal-variable*
387
correctly because there is no way to read a variable object.
388
These forms exist for the sake of the module system.
389
390
Fri Dec 2 19:52:40 1994 Tom Lord (lord@x1.cygnus.com)
391
392
* subr.c (string->obarray-symbol, intern-symbol, unintern-symbol,
393
symbol-set!, symbol-binding)
394
Multiple obarrays.
395
396
* variable.c (scm_make_variable, scm_variable_{ref,set}
397
Implemented variables. Variables are anonymous
398
objects holding one settable value.
399
400
Wed Nov 30 04:31:18 1994 Tom Lord (lord@x1.cygnus.com)
401
402
* *.[ch]: renamed all global identifiers to have the prefix scm_.
403
404
* sys.c (gc_sweep, scm_mark_locations, scm_init_heap):
405
406
Modified gc to allow objects of any multiple of sizeof(CELLPTR).
407
In addition, each heap segment gets to specify a freelist (which
408
may be shared).
409
410
new function: scm_alloc_obj
411
new vars: scm_heap_table (replaces hplims)
412
scm_n_heap_segs (replaces (hpims_ind / 2))
413
414
Thu Oct 27 12:57:02 1994 Aubrey Jaffer (jaffer@jacal)
415
416
From: Jerry D. Hedden <hedden@esdsdf.dnet.ge.com>
417
* ioext.c: conditional code for vms and version (3.6) of Aztec C.
418
* pi.scm ((e digits)): Modified 'bigpi' for slight speed
419
improvement. Added function to calculate digits of 'e'.
420
421
Wed Oct 26 11:22:05 1994 Aubrey Jaffer (jaffer@jacal)
422
423
From: Gary Houston <ghouston@actrix.gen.nz>
424
* scl.c (round): Now rounds as described in R4RS.
425
426
* test.scm (test-inexact): test cases for round.
427
428

452
whether copying is necessary or not. Eliminates gratuitous copy
453

507
Date: Mon, 29 Aug 1994 11:36:46 +0600
508
* unif.c: This is a large patch, but also a bit larger than it
509
appears -- I moved a few function definitions around to eliminate
510
gratuitous forward references.
511
512
* unif.c repl.c (raprin1): Combined print routine for arrays with
513
that for uves.
514
515
* unif.c (UNIFORM-VECTOR-READ! and -WRITE): work with general
516
arrays, by copying when necessary, renamed them to
517
UNIFORM-ARRAY-READ! and -WRITE.
518
519
* unif.c (ARRAY-CONTENTS): Generalized so that it returns a 1-d
520
array even when the stride in the last dimension is greater than
521
one, gave it an optional second argument STRICT, which makes it
522
behave as it did before, returning an array/vector only if the
523
contents are contiguous in memory.
524
525
* unif.c (ARRAY-CONTIGUOUS?) Eliminated. Instead, use
526
(lambda (ra) (array? (array-contents ra #t)))
527
528
* unif.c code.doc (ramapc): unrolls arrays mapping into one loop
529
if possible, to make this quick, changed the format of the array
530
CAR, now uses one bit to indicate that an array is contiguous --
531
this still allows a ridiculous number of dimensions.
532
533
* scm.h (DSUBRF): dsubrs are mapped directly, to allow this I
534
moved the typedef for dsubr and #define for DSUBRF to scm.h
535
536
* unif.c (ARRAY-MAP!) taught something about subrs, now most subrs
537
may be mapped without going through apply(), saving time and
538
reducing consing. +, -, *, /, =, <, <=, >, and >= are mapped
539
directly as special cases -- for uniform arrays this is nearly as
540
fast as the equivalent C, and doesnt' cons. I've made sure that
541
+, -, *, and / vectorize on the CRAY, this may be wasted effort
542
but the effort is not great.
543
544
* unif.c (ARRAY-COPY!) now copies many arrays of differing types
545
to each other without going through the aref/aset, e.g. float ->
546
double, double -> complex, integer -> float ... This should make
547
array type coercions for arithmetic faster.
548
549
* unif.c (TRANSPOSE-ARRAY) Added, which returns a shared array
550
that is the transpose of its first argument. I think this does
551
what an APL:TRANSPOSE would.
552
553
* unif.c (ENCLOSE-ARRAY) Added, this returns an array that looks
554
like an array of shared arrays, the difference being that the
555
shared arrays are not actually allocated until referenced.
556
Internally, the contents of an enclosed array is another array.
557
The main reason for this is to allow a reasonably efficient
558
implementation of APL:COMPRESS, EXPAND, and INDEXING. In order to
559
actually make an array of shared arrays, just use ARRAY-COPY!.
560
561
* unif.c (cvref): Created internal version of aref(), cvref() that
562
doesn't do error checking; Thus speeding things up. Profiling of
563
SCM running array code revealed that aref() was taking a
564
surprising fraction of the CPU time
565
566
TO DO:
567
568
The mechanism for looking up the vectorized functions is a little
569
kludgy, I was tempted to steal some of the CAR of the subr type to
570
encode an offset into a table of vectorized functions, but this
571
would make it more likely that dynamically loaded subrs lose thier
572
names.
573
574
It is almost possible to write APL:+ and friends now, it is just
575
necessary to figure out the appropriate type of the returned array
576
and allocate it, and to promote scalar arguments to arrays (with
577
increments 0).
578
579
This doesn't include vectorized REAL-PART, IMAG-PART,
580
MAKE-RECTANGULAR ...
581
582
I think some C support for APL:REDUCE and maybe INNER-PRODUCT will
583
be needed for a reasonably fast APL.scm
584
585
unif.c is getting quite big, time to split it up?

688
* unif.c: no longer uses pointer comparisons in loops. Should
689
fix problems on 8086 processors.
690
* unif.c (make_sh_array): Fixes MAKE-SHARED-ARRAY so that shared
691
arrays with only 1 element in some direction may still be
692
ARRAY-CONTIGUOUS?
693
(uve_write uve_read): Fixes bug in UNIFORM-ARRAY-WRITE,
694
UNIFORM-ARRAY_READ!. Now they do the right thing for shared
695
bit-arrays not starting at the beginning of their contents vector.
696
(array_contents ARRAY-SIMPLE?): ARRAY-CONTENTS may now return a
697
shared, contiguous, 1-d array, instead of a vector, if the array
698
cannot access all of the contents vector. ARRAY-SIMPLE? removed.
699
(array-fill!): a replacement and generalization of
700
UNIFORM-VECTOR-FILL!.
701
(raequal): Combines with uve_equal(), providing also ARRAY-EQUAL?
702
ARRAY-EQUAL? is equivalent to EQUAL? if all its arguments are
703
uniform vectors or if all are arrays. It differs from EQUAL? in
704
that a shared, 1-d array may be ARRAY-EQUAL? to a uniform vector.
705
for example
706
(define sh (make-shared-array '#(0 1 2 3) list '(0 1))) ==> #1(0 1)
707
(equal? '#(0 1) sh) ==> #F

849
(K&R C does not allow initialization of "automatic" arrays or
850
structures). This was not use in 4d2 or previously, and the
851
following patch ensures that such initialization only occurs for

1875
Comparisons with inexact numbers was not being performed
1876
correctly. For example, (< 1.0 2.0 1.5) would yield #t. What was
1877
missing was a line x=y; in the inexact comparison sections of
1878
lessp(), greaterp(), lesseqp() and greatereqp(). In addition, I
1879
modified these routines and eqp() to allow for mixed arithmetic
1880

2096
2097
* sys.c (gc_sweep): usaage of pclose() now conditional on unix.
2098
2099
* MANUAL (chdir): documented.
2100
2101
from T. Kurt Bond, Adminisoft, Inc. <tkb@MTNET2.WVNET.EDU>:
2102
2103
* repl.c sys.c (errno): VMS GNU C uses a special hack in <errno.h>
2104
to get the link-time attributes for the errno variable to match
2105
those the VMS C run-time library expects (it makes errno a
2106
preprocessor define so that the variable that the compiler sees
2107
has a special form that the assember then interprets), so if it is
2108
VMS and __GNUC__ is defined <errno.h> needs included.
2109
2110
* setjump.h (SETJUMP LONGJUMP): SETJUMP and LONGJUMP changed to
2111
setjump and longjump. The VMS linker is case-indifferent. VMS GNU
2112
C mangles variable names that have upper case letters in them to
2113
preserve their uniqueness.
2114
2115
* sys.c (iprint iprin1): Now inline putc loops instead of calls to
2116
fwrite for VMS. The VMS `fwrite' has been enhanced to work with
2117
VMS's Record Management Sevice, RMS. Part of this enhancement is
2118
to treat each call to `fwrite' as producing a separate record.
2119
This works fine if you are writing to a stream_LF file or an
2120
actual terminal screen, but if you are writing to a file that has
2121
implied carriage control (such as a batch log file, or a mailbox
2122
used for subprocess communication), which is a more common file
2123
organization for RMS, each call to `fwrite' has a newline appended
2124
to it. This causes much of the output to be incorrectly split
2125
across lines.
2126
2127
* vmsgcc.com: created.
2128
2129
