.CHAPTER RUNOFF COMMANDS 
.INDEX RUNOFF COMMANDS 
.INDEX COMMAND FORMAT 
The following commands will be recognized if they are at the 
beginning of a line started with a period.  Any line in the 
source file beginning with a period is assumed to be one of 
these commands.  If it is not, an error diagnostic will be 
typed and the line will be ignored.  Some commands take one 
or more decimal numeric arguments. These are separated from 
the command by a space. 
Multiple arguments may be separated by spaces,tabs, or commas. 
If the parameters are separated by commas, any number of tabs or spaces
may appear before or after the comma.
If the argument is preceeded by a minus sign (-) then it may be entered as 
a negative value.  If it is preceeded by +- then it may be a relative 
argument.  A relative argument changes the old value by the + or - the value 
specified. 
Square are [] brackets are used to denote optional syntax elements. 
.p 
More than one command may be entered on a single line.  The commands may be 
optionally separated by a semicolon (;). 
If the semicolon is used as a separator the next command must immediately 
follow with no intervening spaces. 
Commands which are followed by text must be the last command on a line, 
and may not have other commands after them on the same line. 
These include:
.ts 17,32,47,62 .nj.dhy .lm+2

.lm.j.ehy
For example the following line is a legal set of commands all on 1 line: 
.s.i5;_.TP 10 .Fill;.EH _.Title GONE WITH THE WIND 
.p
Multi-word commands may appear in any form. Thus, 
_.NO HEADER and _.NOHEADER are both legal. 
Many commands may be abbreviated. Standard abbreviations are given 
below each command. 
.p; Commands may have text following them provided the text is separated 
from the command by a semicolon (;).  For example the following line will 
produce a centered title. 
.i5; _.C; THIS IS A TITLE 
.br; The semicolon is essentially a separator which indicates that the rest 
of the line is to be treated just as if a new line had begun. 
.p
.text
For example the following forms of the _.PAGE SIZE command area all
legal.
.nf.lm+5
_.PAGE SIZE 20,20
_.PAGE SIZE 20 , 20
_.PAGESIZE 20 20
_.PS ,,1,2
_.ps , , 1 2
.lm.f
.end text
