PlanetPress Alambic is the name of the RIP built in to PlanetPress (the RIP PlanetPress uses when you perform a preview and
select Internal interpreter as the PostScript interpreter).
version
String value containing the version number of the RIP the document is using to execute. For example, 4.0.
formversion
Integer value containing the version number of the document requested by the trigger. Recall that you can assign a version
number to a document and increment the number each time you update and reinstall the document. When you execute a doc-
ument that uses a version number, the document verifies its version number against the one you specify in the trigger, and it
proceeds with execution only if the two version numbers match. See the PlanetPress User Guide for more complete infor-
mation on versioning.
&Width (system variable)
System variable with a scope local to a specific object or group. The system initializes this variable to the value of the Width
property of the object’s or group’s Basic Attributes. You can reference and set this variable in any PlanetPress Talk code you
enter in the object, group, or page.
Syntax
&width measure value
@ (function)
Returns a selection within the current data page for text emulations.
The@ character can be the beginning of a data selection, a page call or a procedure or function call.

Arguments

a value inside the data page and sets a Boolean variable according to the results.
