GoIfInOff ii+,LLLL

PC = (input ii) ? (PC+1) : LLLL

(A FastTrack instruction)

This instruction tests the nominated input ii. If the input is off, the program will go to (jump to) the program line with the label LLLL. If the input is on, the program will continue at the next instruction.

This instruction uses debounced inputs. Debounce adds a delay of 8 to 20mS to the input response, in order to reject contact bounce (chattering) in mechanical input switches.

+ From dialect 16 the address argument will be jndexed when executed inside a MultiTrack task and will be indexed if the instruction is preceded by the IasJ: precode.

Dialect restriction: This instruction is not implemented on boards prior to dialect D=7, but can be used on older boards via automatic translation by SPLat/PC.
