This section describes the CST-Postgen model, which is used to create the pre-generation subprogram for a model. The post-generation subprogram supplies values for the substitution parameters in the code frames, which is the final stage of the generation process.
This section covers the following topics:
After defining the pre-generation subprogram, use the CST-Postgen model to generate the post-generation subprogram. This subprogram supplies values for substitution parameters in the code frames (identified by &). It is invoked as the final stage of the generation process when the application developer enters "G" in the Function field on the Generation main menu.
The post-generation subprogram substitutes the code frame parameters
with the corresponding substitution values by stacking the substitution
parameters and their corresponding values. Use the STACK TOP DATA
FORMATTED statement to stack these values. Natural Construct performs
the corresponding substitutions in the edit buffer and produces the final
version of the generated program.
During the generation process, code lines specified in the code frame are written to the edit buffer, as well as the output of the generation subprogram contained in the code frame. Any substitution parameters are included in the edit buffer exactly as they appear in the code frame.
Note:
For an example of a generated post-generation subprogram, refer to
CUMNPS in the SYSCST library.
Use the CST-Postgen model to create the post-generation subprogram. This model has one specification panel, Standard Parameters.

The input fields on the Standard Parameters panel are:
| Field | Description |
|---|---|
| Module name | Name specified on the Generation main menu. The
name must be alphanumeric and no more than eight characters in length. Use the
following naming convention:
CXxxPS where xx uniquely identifies your model. |
| Model name | Name of the model that uses the post-generation
subprogram.
Note: |
| Title | Title for the generated subprogram. The title identifies the subprogram for the List Generated Modules function on the Generation main menu and is used internally for program documentation. |
| Description | Brief description of the subprogram. The description is inserted in the banner at the beginning of the subprogram and is used internally for program documentation. |
