Open ServerConnect Programmer's Reference for COBOL

Appendix B: Sample RPC Application for CICS

Appendix B

This appendix contains five Open ServerConnect application programs:

• Sample Program SYCCSAR2

  A sample application that processes a LAN-side RPC from the Open Client DB-Library

• Sample Program SYCCSAU2

  A sample cursor application

• Sample Program SYCCSAW2

  A sample application that receives parameters up to 55 bytes in length and echoes them back in 55 byte rows

• Sample Program SYCCSAY2

  A sample application that receives one of two keywords, @ERRORMSG or @WARNMSG and other keywords, and then replies with the keywords and data

• Sample Program SYCCSAZ2

  A sample application that receives a text input string (10,000 bytes) and returns it in a 50 byte column one row at a time

The purpose of these sample programs is to demonstrate the use of Gateway-Library functions, particularly those designed to handle remote procedure calls from a client. 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 programs do limited error checking.
