Composite Module Testing

Composite support lets you take advantage of all CA InterTest for CICS functions when you test composite modules. A composite module consists of separately compiled modules link‑edited in one load module. These modules can be written in different languages and compiled at different times. Composite support lets you test and debug a called subroutine as if it were a separate program—with full symbolic support.

Example

Suppose a PL/I program has several subroutines, some written in PL/I, some written in Assembler and PL/I. You can test and debug any of the subroutines just as if it were a main program by setting breakpoints, setting monitoring options, displaying the source listing, and displaying and modifying main and auxiliary storage.

A composite module can be defined using one of two methods:

Execute batch program IN25LINK after the link edit step for the composite module
Specify the COMPOSITE command in the Source Listing Display before monitoring is activated for the program

When you set monitoring for a composite module defined by the IN25LINK method, CA InterTest for CICS informs you that composite support can be set, as shown in the following screen.

When you press PF3, CA InterTest for CICS displays the link‑edit information for the main program and its subroutines. You can change this information online.
