This command in combination with a LOOP command creates a program loop. The
number of loop cycles (> 0) is specified as a constant. The loop ends at the associated
LOOP command. Program loops can be nested.
If the number of loop cycles is to be variable, a JMP command must be used instead of
a LOOP command and the variable condition must be checked at each cycle.
