Token Rules

Tokens are character strings, within a set of PPFA commands, that PPFA recognizes as units. Tokens include:

• Both local names and user-access names for fonts, form definitions, page definitions, overlays, and suppressions
• Commands
• Subcommands
• Parameters
• Literals
• Special characters

The only PPFA element that is not a token is a blank. A token cannot be split between two lines.

To create a token, you must separate a string from the previous token by either a special character or a blank. See the list of special characters in Character Set. Thus, A+B is the same as A + B, because + is a special character. But AB is not the same as A B. The blank in A B creates two tokens.
