Copying Members Have Alias Names

Copying Members Have Alias Names

Summary

The COPY or COPYGRP statement is used to copy a PDS or PDSE with members with alias names.

Rules -

  • All members with their aliases are copied if they copy an entire PDS to a new one.
  • If merging a PDS with another, members or aliases will not change on the output PDS.
  • When selectively copying from a PDS, we need to specify every name, including their aliases.
  • To exclude a member, we should specify that member's name and all of its alias names to exclude it from the copy operation.

Practical Example -

Scenario - Copying member (COPY) and its alias (COPYALIA) from one PDS to another.

Input -

Explaining Example -

  • SYSUT1 DD DSN=MATEPK.IEBCOPY.INPPDS - Specifies the input PDS.
  • SYSUT2 DD DSN=MATEPK.IEBCOPY.OUTPDS - Specifies the output PDS.
  • COPYGRP INDD=SYSUT1,OUTDD=SYSUT2 - Copies members from SYSUT1 to SYSUT2.
  • SELECT MEMBER=(FIRSTPRG,FSTALIAS) - Copies member FIRSTPRG and its alias FSTALIAS from SYSUT1 to SYSUT2.
