TCP/IP Programming Support for Online Applications

TCP/IP programming support within CA IDMS allows an application to communicate through TCP/IP protocols with a second application. The second application can reside on the same platform or another platform.

The socket program interface depends upon the programming language used to write the application:

• Programs written in Assembler use the #SOCKET macro interface.
• Programs written in COBOL or PL/I use a call interface to IDMSOCKI.
• Applications written in CA ADS can use the SOCKET built-in function or the call interface to IDMSOCKI.

For sample TCP/IP programs written in these programming languages, see TCP/IP Programming Examples.

More Information:

• A TCP/IP trace facility is available to assist you in debugging socket programs. It is enabled using the DCMT VARY LTERM command. For more information, see the CA IDMS System Tasks and Operator Commands Guide.
• IDMSIN01 provides a string translation function to convert data from EBCDIC to ASCII format and from ASCII to EBCDIC format. For more information, see the chapter IDMSIN01.
