7.3.2.1 Syntax

Every command name begins with a backslash (‘\’). If the command uses an argument, it is given between curly braces with no spaces between the command name and the argument.

The main limit on PreScript is that no command can be used inside another command. For instance the following line will be badly interpreted by a2ps:

\Keyword{Problems using \keyword{recursive \copyright} calls}

The correct way to write this in PreScript is

\Keyword{Problems using} \keyword{recursive} \copyright \Keyword{calls}.

Everything from an unquoted % to the end of line is ignored (comments).
