N10010 DELAYFSTON()

N10020 R1 = R1 + 1

N10030 G4 F1

N10040 subroutine2

N20010 DELAYFSTON()

N20020 DELAYFSTOF()

N10050 DELAYFSTOF()

N10060 R2 = R2 + 2

N10070 G4 F1

Program segment example

The following program block is repeated in a loop:

;blocks with N10xxx program level 1

;stop delay section starts.

;interpretation of subroutine 2

;no effect, restart, 2nd level

;no effect, end in other level

;end of stop delay section in same level

;stop delay section ends.

;stops now have direct effect
