The Definition Command Language

The command language for the definitions is very simple. Each line has the form

 
command-name replacement-text 

%

Output the % character

1

Insert the first string argument

2

Insert the second string argument

3

Insert the third string argument

4

Insert the fourth string argument

i

Insert the first integer argument

n

Insert a newline only if not at an newline

u1

Insert the first string argument, but in uppercase. Similarly for u2 through u4.

p

Insert end-of-paragraph string only if not at an end-of-paragraph.

f

Insert the end of font string. This string is defined by the %e= command.

N="..."

Replace newlines with the string given in quotes. The string can be 32 characters or less.

e="..."

Define the end of font string. The string can be 32 characters or less.

m="..."

Define the output mode. This is a string that is understood by the particular output format. For example, the LaTeX output routines understand the mode verbatim and use that to change how characters are output.

a0="..."

Define the value of string register zero. The string may be up to 63 characters long. There are 10 registers, commands a1 through a9 access the other nine. The value of a0 is set to the name of the function or macro by doctext, and normally should not be changed.

r1

Insert the value of string register zero. Similarly for r1 through r9.

Sometimes you will not want to replace a command; instead, you will want to insert your replacement text either before or after the standard text. You can do this by placing a + either before or after the command-name. An example of this is in SectionAlternate Formatting for HTML .
