Example of channel name and channel number with integer variable
$MC_CHAN_NAME[0]= "CHAN_X"
$MC_CHAN_NAME[1]= "CHAN_Y"
START(1, 2)
Similar to this, programming with the channel identifiers:
START(CHAN_X, CHAN_Y)
Programming with an integer variable:
DEF INT chanNo1, chanNo2)
chanNo1=CHAN_X chanNo2=CHAN_Y
START(chanNo1, chanNo2)
1-44
;Run start in 1st and 2nd channel
;Run start in 1st and 2nd channel
;The channel_X and channel_Y identifiers
represent $MC_CHAN_NAME internally due to the
machine data, channel numbers 1 and 2 also run
a start in the 1st and 2nd channel accordingly.
;Define channel number
