Roger, The sequence block will not actually stop running until it hits a suspension statement (WAIT, external reference, etc.) or executes the maximum number of statements (BPCSTM). Put a WAIT statement after the ABORT to immediately stop normal execution. The TO_INACTIVE SBX logic will start running the next scan period.

It seems to continue to execute some of the code following the abort line. I think the ABORT command simply toggles the ACTIVE bit. Does the block not respond immediately to the toggling of the ACTIVE bit? Has anyone run across this or have any ideas? The block also has a "TO INACTIVE" exception handler which seems to work.
