Copy Control Block Modifications

Modify only the VSAMPL and DDESCR control blocks. For the VSAMPL control block, you are required to modify the VSRTNCD and VSMSGID fields as follows:

  • Set the VSRTNCD field (and R15) to 0 to allow the Copy step to execute.
  • Set the VSRTNCD field (and R15) to a nonzero value to fail the Copy step.
  • Insert a message ID into the VSMSGID field, if the VSRTNCD is set to a nonzero value. Take precaution to avoid duplicating existing message IDs.
  • Place the message text corresponding to these message IDs in the IBM® Connect:Direct® message file.
