TCP/IP Coding Samples

The CA IDMS installation media contains these sample programs, which are intended for demonstration purposes only:

• TCPASM01—An Assembler program that tests the #SOCKET API calls. TCPASM01 can be invoked in one of two ways:
  • As a user task code at the "ENTER NEXT TASK CODE" prompt. Depending on the command line parameters, a client or server program is initiated. The program converses with a partner program using SEND and RECV calls. If no parameters are specified, a HELP screen containing the full syntax and its options is displayed.
  • As a server program started by a listener PTE.

    Note: The listener's PTERM definition should specify MODE is USER.

• TCPADS01—A TCP/IP client program written in CA ADS.
• TCPCOB01—A TCP/IP generic listener server program written in COBOL.
• TCPPLI01—A TCP/IP generic listener server program written in PL/I.

TCPADS01 and TCPASM01 (as a client) provide the same functionality: they connect to a port number that matches a port number of a generic listener PTERM. TCPPLI01, TCPCOB01, and TCPASM01 (as a server) can be invoked by the task code associated with the generic listener PTERM.

Note: The header section of each sample program contains compiler option information that is required to successfully compile the program.
