Program code
N70 mySubProgrammA
N80 DO $AC_PROG_NET_TIME_TRIGGER=1
N95 ENDFOR
N97 mySubProgrammB
N98 M30
After the program has processed line N80, the net runtime of "mySubProgrammA" is located
in $AC_OLD_PROG_NET_TIME.
The value from $AC_OLD_PROG_NET_TIME:
● Is kept beyond M30.
● Is updated each time the loop is run through.
