    Wild card/s for numeric, alpha characters

    Looking for a DFSMS/HSM exit point of RACF Control

    Support SHAREOPTIONS when creating a VSAM with JCL

    We are trying to use the JCL DD statement to create some VSAM Data Sets to remove the extra IDCAMS DEFINE steps in some jobs. It is working quite well, especially if we are using the LIKE parameter to get most of the properties from 'model' VSAMs....
