That prevents the next block in the calling programfrom already running. If a single-block suppression is activated in a subprogram with SBLOF,without SBLOF in the PROC instruction, execution is only stopped after the next machinefunction block of the calling program. If that is not desired, SBLON must be programmed in thesubprogram before the return (M17). Execution does not stop for a return jump to a higher-levelprogram with RET.Example:Program code CommentN10 X0 F1000 ; Execution is stopped in this block.N20 UP1(0)K1: Mode group, channel, program operation, reset response9.13 Single blockBasic FunctionsFunction Manual, 01/2015, 6FC5397-0BP40-5BA2 585
