Single block suppression for the complete program
Programs designated with SBLOF are completely executed just like a block when single
block execution is active, i.e. single block execution is suppressed for the complete program.
SBLOF is in the PROC line and is valid up to the end of the subprogram or until it is
interrupted. At the return command, the decision is made whether to stop at the end of the
subprogram:
Return jump with M17:
Return jump with RET:
Single block suppression within the program
SBLOF alone must remain in the block. Single block is deactivated after this block until:
● To the next SBLON
● To the end of the active subprogram level
