Introduction › Types of CA Culprit User Modules

Types of CA Culprit User Modules

CA Culprit user modules are subroutines that perform tasks beyond the scope of standard CA Culprit processing. The CA Culprit installation media includes a wide range of user modules, which are summarized at the end of this section. Site-specific routines can also be written, stored, and called from CA Culprit code. Instructions for developing your own user modules can be found in "Writing User Modules" chapter.

Before invoking or writing user modules, you should be familiar with CA Culprit coding techniques. Refer to the CA Culprit for CA IDMS User Guide and to the CA Culprit for CA IDMS Reference Guide for detailed information on coding CA Culprit parameters.

A user module can be one of three types:

• The input module, which reads an input file by using information supplied on an INPUT parameter.

  An input module is processed during the extract phase (CULL step, as shown in the diagram below) of a CA Culprit job to read one or more files, manipulate input data, and build the CA Culprit input buffer.

• The procedure module, which performs type 7 processing on user-supplied data and returns the processing results to user-defined fields.

  A procedure module is processed during the extract phase (CULL step) of a CA Culprit job.

• The output module, which creates an output file or report formatted to user specifications.

  An output module is processed during the output phase (CULE step) of a CA Culprit job, as shown below.

CA-supplied and user-written input, procedure, and output modules are discussed in detail in the following sections.

Input and procedure modules are processed only during the CULL step.

Output modules are processed only during the CULE step.
