    Chris, If you have the 'NODYNAMIC' option specified for the program,
    then you can't have multiple versions. Try specifying DYNAMIC for the
    program statement.

    From the Sysgen Manual:

    Allows users to define additional versions of the program at runtime
    either by

    means of the DCMT VARY DYNAMIC PROGRAM command or, if the program

    is eligible for automatic definition, through the definition of null
    PDEs on the

    SYSTEM statement.

    DYNAMIC is the default when you specify neither DYNAMIC nor

    NODYNAMIC in the PROGRAM statement.


    Prevents users from defining additional versions of the program at

    Additionally, the system generation compiler ensures that only one
    version of the

    program is included in the system definition.

    We are running 16.0 SP1 + many apars on z/OS 1.8 and have a need to
    create a non-version 1 DC-COBOL program to test an emergency that only
    happens in Production. When we try the DCMT VDP it threw a DC273912 V1
    Multiple Versions of program XXXXXXXX are not allowed. Entering DCMT D
    MESS DC273912 we get this The user attempted to add a program definition
    dynamically, but the program is defined at system generation time with
    the MULTIPLE VERSIONS NOT ALLOWED attribute. This does not appear in the
    syntax for Program or System in the sysgen. We can do this on
    Development where we use multiple versions but can't seem to get a
    handle on where we have defined this in Production. =20


    Anyone know the magic sysgen parameter that we must have set differently
    in production to development?

    "I thought that to have a version 2 of a DC-Cobol program you needed a
    //CDMSL0002 DD statement pointing to your ver 2 load library, and if you
    wanted a version 99 DC-Cobol you needed a //CDMSL0099 DD statement. You
    do not need to specify NODYNAM on the version 1 sysgen definition, but
    you will need to specify a version 2 and a version 99 sysgen definition
    for the program.

    What the NODYNAM specification does is prevents a search for a currently
    loaded load module through the loadlist - so that for example let's say
    you have loaded an ADS dialog from a load library, and there is a
    dictionary higher up in the loadlist then DC loader will look at any all
    dictionaries and load libraries that are ""higher up"" in the load list
    sequence to see if there is a ""dynamic"" version of the load module
    available. By specifying NODYNAM you prevent this non-essential
    additional searching for programs that you only ever want to be loaded
    from a specific location.

    That's my understanding - if it's wrong I'd love to be corrected because
    in the past I've made tuning decisions on the basis of this
    understanding - cheers - Gary=20
