It is not necessary to regenerate an entire application system when moving from one TP monitor to another. For example, only reinstallation is required when moving from TSO to CICS. Be careful not to install load modules containing action blocks that are generated with the debug option into IMS or CICS.
Regeneration is required to move from one TP monitor to another when one of the TP monitors is IMS. The screen modules that are generated for BYPASS differ from those generated for MFS in the handling of literals and prompts. Therefore, screen modules must be generated when moving from TSO or CICS (BYPASS) to IMS (MFS) or vice versa.
When installing RI Triggers or Action Blocks statically called by modules that are marked for Compatibility, use the option Process modules that are marked for Compatibility to ensure that the compile is done using the NODLL option.
