You can use the IEBCOPY utility program to copy a program module from one program library to another. IEBCOPY can also perform conversions between load modules and program objects. IEBCOPY can be used to copy a program module from a partitioned data set program library to a PDSE program library. IEBCOPY converts the new copy into the format appropriate for the target program library. However, you cannot convert a program object into a load module and store it in a partitioned data set library if the program object exceeds the limitations of load modules (for example, if its length is greater than 16 MB).

The control statement, COPYGRP, allows you to copy a program library member (load module or program object) and all of its aliases, specifying only a single name. Since member and alias names are still limited to eight bytes in IEBCOPY control statements, COPYGRP is required for copying members with long alias names.

You can also use the IEBCOPY utility to alter relocation dictionary (RLD) counts of load modules in place, and to reblock load modules. You do not need to alter RLD counts for program objects, or use the COPYMOD control statement to change the block size of a program object library. The COPYMOD control statement reblocks load modules to a block size best suited for the target device, reducing the time it takes to load a program into virtual storage.
