A sample UIM is provided in SYS1.SAMPLIB(CBDSUIM). Use this sample as the basic structure for your HCD UIM. SYS1.SAMPLIB(CBDSUIM) contains:

• Overview of contents
• Sample code for DASD units with detailed comments
• The JCL to assemble and link-edit the UIM

  Be sure to include the correct SYSIN and SYSLMOD data set names. Define the SYSLMOD data set as SYS1.NUCLEUS.

  Note:
  To test the UIM, do not link it into SYS1.NUCLEUS. Instead, before testing the UIM, link it to another library and concatenate that library to the HCD load libraries. Specify that library on the UIM_LIBNAME parameter in the HCD profile statement.

  UIM_LIBNAME=Name of data set containing the UIMs

  All UIMs (and UDTs) are loaded from the specified data set (SYS1.NUCLEUS is the default)

  UIM_LIBNAME=*

  The UIMs are contained in the HCD load libraries. In this case, the data set containing the new UIM and SYS1.NUCLEUS containing the existing UIMs must be concatenated to the HCD load libraries using STEPLIB/JOBLIB statements.

  Test the UIM as described in Testing UIMs.
