Suppress single block execution (SBLOF, SBLON)

Function
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
or
• To the end of the active subprogram level
