Command Nesting Rules
- FONT commands must be specified immediately after PAGEDEF commands.
- A SETUNITS command can be specified anywhere in the PPFA command stream and is in effect until another SETUNITS command is specified.
- OBJECT commands may appear after the FONT command, before any PAGEFORMAT command (global objects) or after a specific PAGEFORMAT command. A global object is defined for all page formats in the page definition. Otherwise the object is just defined for the PAGEFORMAT in which it is specified.
- TRCREF, SEGMENT, and OVERLAY commands must be specified under their associated PAGEFORMAT command.
- The first PAGEFORMAT command can be omitted in a page definition, if the page definition has only one page format.
- At least one PRINTLINE command is required.
