UNDO primary command

The UNDO primary command allows you to roll back all your editing changes since the last checkpoint.

Syntax


1 UNDO
Issuing the UNDO command on the IMS data panel backs out all your editing changes since the last checkpoint. This is provided that you are editing in BMP mode or, if you are editing in DLI mode, the following conditions are true:
  • The IMS log option on the DLI Mode Parameters panel is set to 1. Keep, 2. Keep when updates, or 3. Delete.
  • The Dynamic backout option on the DLI Mode Parameters panel is selected.
  • The Edit is using either a dynamic PSB or a static PSB that has an IO PCB.
If you are editing in DLI mode and one or more of these conditions is not true, FM/IMS issues an error message.
