  • The power of the High Level Assembler language can be extended by adding REXX to its capabilities. This session provides a practical example of how to implement a SETCF function that invokes any REXX function the during the assembly.
     
    The HLASM SETCF function passes arguments to a module that returns a string of data. The module that we demonstrate provides a mechanism for invoking a REXX exec and returning an error  indication from the exec and a string. We also demonstrate saving global variables between SETCF invocations.  

    Some useful execs:
    1)      Use PARSE to decode macro variable strings
    2)      Return the contents of datasets
    3)      Communicate with databases during assembly
