Language and Conventions Overview
Global Parameter Access (GPA) symbols provide a means of accessing certain functional data which is used by the NX system.
A GPA symbol always begins with a ampersand (&) and is a maximum of six characters long. GPAs are defined in the system and may not be altered.
Each GPA symbol is associated with either a unique global parameter or a constant and has an access type, a data type, and a data range. The following list contains a few of the GPA symbols which are available:
