SC27-3660-00

This section provides information about the sample programs that show how to use the REXX socket API. These programs are provided as is.

  • Overview of REXX sample programs
    The sample programs and the jobs that you can use to run them are located in the SEZAINST file.
  • The REXX-EXEC RSCLIENT sample program for IPv4
    The client sample program is a REXX socket program that shows you how to use the commands that are provided by the REXX sockets API. The program connects to the server sample program and receives data, which is displayed on the screen. It uses sockets in blocking mode.
  • The REXX-EXEC RSSERVER sample program for IPv4
    The server sample program shows an example of how to use sockets in nonblocking mode. The program waits for connect requests from client programs, accepts the requests, and then sends the data. The sample can handle multiple client requests in parallel processing.
  • The REXX-EXEC R6CLIENT sample program for IPv6
    The client sample program is a REXX socket program that shows you how to use the commands that are provided by the REXX sockets API. The program connects to the server sample program and receives data, which is displayed on the screen. It uses sockets in blocking mode.
  • The REXX-EXEC R6SERVER sample program for IPv6
    The server sample program shows an example of how to use sockets in nonblocking mode. The program waits for connect requests from client programs, accepts the requests, and then sends data. The sample can handle multiple client requests in parallel processing.
  • AT-TLS security definitions for REXX samples
    When Application Transparent Transport Layer Security (AT-TLS) is enabled on the TCP/IP stack, you must define the REXX sample applications to the Policy Agent.
  • Running the REXX sample programs
    This topic describes how to run the REXX sample programs.
  • Testing the GIVESOCKET and TAKESOCKET commands
    This topic describes how to test the GIVESOCKET and TAKESOCKET commands using the sample programs.
