FDTLOADR Utility

The FDT can be converted from a sequential data set to a load module by using the FDTLOADR Utility. Because sequential FDTs are not supported by CA Compress Transparency or SUBSYS, the Interactive User Interface performs this function automatically.

Note: FDT member names must be unique within a PDS library containing FDTs and unique across the installation. It is extremely dangerous to have more than one FDT with the same name.

Because FDTs in load module format must be accessed in a slightly different way from sequential FDTs, converting existing FDTs to load module format requires minor modifications to the application programs. These differences are discussed in Accessing the FDT in this chapter, and in the descriptions of the FDT parameter in the detailed discussions of the SHRINK and EXPAND subroutine calls.

Conversion to load module format offers the following benefits:

• Compatibility with CA Compress, which does not support sequential FDTs.
• Access to all FDTs through STEPLIB instead of having to code a separate TABLxx DD statement for each FDT.

Member SHR2FLDR in the distribution JCL executes the FDTLOADR utility. The TABL00 DD statement defines the FDT in sequential data set format. The SYSLMOD DD statement defines the PDS library and the member name in which the FDT is to be stored in load module format.
