6
2.02 Coding bug in open.c repaired
7
2.03 fixed bugs in lread.c (read * with negative f-format) and lio.c
8
and lio.h (e-format conforming to spec)
9
2.04 changed open.c and err.c (fopen and freopen respectively) to
10
update to new c-library (append mode)
11
2.05 added namelist capability
12
2.06 allow internal list and namelist I/O
17
allow upper-case STATUS= values
19
create fort.nnn if unit nnn not open;
20
else if (file length == 0) use creat() rather than copy;
21
use local copy() rather than forking /bin/cp;
22
rewind, fseek to clear buffer (for no reading past EOF)
24
use neither setbuf nor setvbuf; make stderr buffered
29
omit byfile test from SEQUENTIAL=
30
answer "YES" to DIRECT= for unopened file (open to debate)
32
flush stderr, stdout at end of each stmt
33
space before character strings in list output only at line start
35
adjust LEW, LED consistent with old libI77
38
allow "nnn*," when reading complex constants
40
try opening for writing when open for read fails, with
41
special uwrt value (2) delaying creat() to first write;
42
set curunit so error messages don't drop core;
43
no file name ==> fort.nnn except for STATUS='SCRATCH'
45
use atof(); trust EOF == end-of-file (so don't read past
46
end-of-file after endfile stmt)
48
flush stderr, stdout at end of each stmt
51
put wrt_E and wrt_F into wref.c, use sprintf()
52
rather than ecvt() and fcvt() [more accurate on VAX]
