DF2-Related Variables
The DF2 configuration file contains a large set of parameters used to define how GPP2 operates in a given post-processor. Many of these parameters have associated system variables that can be accessed or modified in the EX2 program. These variables can also be used in the post-processor interaction in order to allow the end-user to change some of the values.
These DF2-associated system variables are described in this section.
The data flow is as follows:
The DF2 file is loaded into GPP2 (as part of a post-processor load).
The relevant system variables are initialized with the DF2 data.
If specified as interaction variables, they are shown to the end-user. Any changes made by the end user take place before the post is executed.
The EX2 program may make use the data or make additional changes throughout the execution.
Note: Changes made to DF2-related variables in the STARTUP block take effect before any of these variables is used in the execution process.
