This appendix contains a sample mainframe server application program that a system programmer can use to perform mainframe-based tracing and accounting functions.
This program is not included on
the Open ServerConnect tape.
The purpose of this sample program is to demonstrate the use of all Gateway-Library tracing and accounting functions. In some cases, one Gateway-Library function is used for demonstration purposes when another function would be more efficient. In order to best illustrate the flow of processing, the program does not do extensive error checking.
This sample program uses VS COBOL II and Gateway-Library and runs under CICS.
This program demonstrates the use of the following Gateway-Library functions listed in Table G-1.
