91
This document describes
92
in extremely terse form
98
Some familiarity is assumed
102
the reader should understand
106
the use and definition of number registers
108
how to define macros,
109
and scaling factors for ens, points,
111
(vertical line spaces),
114
For a more casual introduction
117
refer to the document
119
Writing Papers with \*G using \-me.
121
There are a number of macro parameters
122
that may be adjusted.
123
Fonts may be set to a font number only.
124
Font 0 is no font change;
125
the font of the surrounding text
127
Notice that font 0 is a
130
it is simulated by the macros.
131
This means that although it is legal to set a font register
133
it is not legal to use the escape character form,
141
so it is nearly always necessary
142
to use a scaling factor.
145
to set the paragraph indent
146
to eight one-en spaces is:
154
which would set the paragraph indent to eight basic units,
156
Default parameter values are given in brackets
157
in the remainder of this document.
159
Registers and strings
163
may be used in expressions
164
but should not be changed.
168
perform some function
171
to change this function.
172
This may be a sensitive operation;
173
look at the body of the original macro
177
follow a rigid naming convention.
178
The user may define number registers,
182
uses single character upper case names
183
or double character names
184
consisting of letters and digits,
185
with at least one upper case letter.
186
In no case should special characters
187
be used in user-defined names.
188
Locally defined macros
189
should all be of the form
195
(upper or lower case)
198
This documentation was \*G'ed
200
and applies to \*G version
205
These macros are used
207
The standard paragraph macro
210
the others are all variants
211
to be used for special purposes.
213
After the first call to one of the paragraphing macros
214
defined in this section
218
(defined in the next session),
219
the effects of changing parameters
220
which will have a global effect
221
on the format of the page
222
(notably page length and header and footer margins)
224
and should be avoided.
228
Begin left-justified paragraph.
229
Centering and underlining
230
are turned off if they were on,
268
This is the standard paragraph macro.
276
The body of the following paragraph
287
more than a non-indented paragraph
293
is exdented (opposite of indented).
294
The result is a paragraph
295
with an even left edge
298
printed in the margin.
304
will not fit in the space provided,
306
will start a new line.
310
A variant of .ip which numbers paragraphs.
317
The current paragraph number
325
except that paragraphs are marked with bullets (\(bu).
326
Leading space is eliminated to create compact lists.
327
.sh 1 "Section Headings"
330
are similar to paragraphs
334
generated for each one.
335
The section numbers are of the form
340
is the count of numbers
341
(separated by decimal points)
342
in the section number.
344
Unnumbered section headings are similar,
345
except that no number is attached
353
Begin numbered section
365
the individual parts of the section number
373
space before the section.
385
of the section may be accessed via
393
times the section depth,
394
and the section title
399
an additional indent of
402
is added to the section title
403
(but not to the body of the section).
405
to the paragraph font,
406
so that more information may occur
408
with the section number
411
insures that there is enough room
412
to print the section head
413
plus the beginning of a paragraph
414
(about 3 lines total).
420
the section number is set to that number
421
rather than incremented automatically.
427
that number is not reset.
430
is a single underscore
433
then the section depth and numbering is reset,
434
but the base indent is not reset
435
and nothing is printed out.
436
This is useful to automatically
437
coordinate section numbers with
447
but do not print the number
449
and do not increment the section number
453
of starting a new paragraph
460
Unnumbered section heading.

Print section heading.

484
is the section number for this section,
487
is the depth of this section.
488
These parameters are not always present;
493
passes only the first,
499
Care should be taken if this macro
501
it is quite complex and subtle.
508
This macro is called automatically
511
It is normally undefined,
515
into the table of contents
516
or for some similar function.
519
for the section title which was just printed,
521
is the section number,
524
is the section depth.
530
Traps called just before printing that depth section.
533
give variable spacing
535
These macros are called from
537
so if you redefine that macro
538
you may lose this feature.

A normally undefined macro
715
at the top of each page
718
initial saved floating keeps,
721
this macro is called immediately before
724
It can be used for column headings
728
All displays except centered blocks
730
are preceded and followed
736
Quote spacing is stored in a separate register;
737
centered blocks have no default initial or trailing space.
738
The vertical spacing of all displays except quotes
740
is stored in register
750
Lists are single spaced,
756
the list will be filled.
763
the list is indented by

the list is indented to the left margin;
771
the list is left justified with respect to the text
774
only if the base indent
782
the list is centered on a line-by-line basis.
783
The list is set in font
788
This macro is almost like
790
except that no attempt is made
791
to keep the display on one page.
800
These are single spaced,
802
moved in from the text
807

[one point smaller than surrounding text].

Blocks are not filled

when they are filled.

The block will be left-justified
873
and left justified to the margin

(not to the base indent)

The block is set in font

except that the keep is

The text of the footnote
964
is floated to the bottom
984
from the right margin.
985
Footnotes line up underneath

If the text of the footnote
988
will not all fit on one page
989
it will be carried over
998
and the associated string
1001

The macro to output the footnote separator.
1006
This macro may be redefined
1007
to give other size lines or other types

is finished with a row of dots

right justified on the last line
1046
(such as for an author's name),
1056
can be used to print the current page number.
1071
The index is formatted in the font, size, and so forth
1072
in effect at the time it is printed,
1073
rather than at the time it is collected.
1074
.sh 1 "Columned Output"

Enter two-column mode.
1081
The column separation is set to

1087
calculated to fill the single column line length
1094
You can test register
1097
to see if you are in single column
1098
or double column mode.
1107
Revert to single-column mode.
1114
except that it begins a new column
1117
rather than forcing a whole new page

if there is another column left
1119
on the current page.

The pointsize is set to
