System Variables
&EOJob (system variable)
Read-only variable that returns True if the document has processed the last line of data or if the line that follows the last form
feed character (ASCII 12) is empty.
This variable always returns True at design-time when using a user-defined emulation.
Thus if a file ends with the sequence:
FF CR LF
&eojob becomes true before the last line (CR LF) since the last line is empty.
Syntax
&eojob Boolean value
&FirstSide (system variable)
Read-only variable that returns True when a page is printing on the first side of a page in duplex mode (double-sided printing).
In simplex mode (single-sided) &firstside always returns True.
This variable is based on PostScript’s firstside command as implemented in your printer. If your printer does not support
firstside, the document attempts to detect which side of the page is currently printing. Passthrough commands can hamper
the document’s ability to return the correct value for &firstside.
Syntax
&firstside Boolean value
&Height (system variable)
System variable with a scope local to a specific object, group, or page. The system initializes this variable to the value of the
Height property of the object’s, group’s, or page’s Basic Attributes. You can reference and set this variable in any PlanetPress
Talk code you enter in the object, group, or page.
Syntax
&height measure value
