The CTBSSM program, a sample assembler program, illustrates how to call a Control-M/Analyzer rule from a user program using the Single Startup API. This program is a member in the IOA SAMPLE library.
The program reads an input file using DD-USERIN, passes each record to Control-M/Analyzer that in turn executes the TSTCHECK rule to validate the record. As a result, the TSTCHECK rule returns TOLER (return code) that is being printed in the main cycle of the program illustrated in Figure 415.

PLEASE FILL IN RULE DEFINITION. 13.54.17
The TSTCHECK rule receives the parameters RARG01 – RARG03 from Control-M/Analyzer.
The RARG01 parameter contains the record to be checked. The RARG02 parameter points to the LINEID (record logical sequence number). The RARG03 parameter refers to TOLER (return code). The values RARG01 and RARG03 can be changed by TSTCHECK and their updated values are passed to the USER PROGRAM. Changes in the RARG02 parameter are not returned to the USER PROGRAM.
Input for the USERMAIN Assembler program (sample user program CTBSSM) is illustrated in Figure 417.
Note: This is sample code for documentation only. Please refer to the IOA SAMPLE(CTBSSSM) for the complete source code to be used.
