13.3.3 Jump within the Main Program
The use of instruction
M99
in the main program will produce an unconditional jump to the first block of the main program, and
the execution of the program will be resumed there. The use of this instruction results in an endless
cycle:
The use of instruction
M99 P.....
will produce an unconditional jump to the block specified at address P of the main program, and the
execution of the program will be resumed there. The use of this instruction results in an endless cycle:
The possibility of endless cycles can be avoided by specifying the block containing instruction M99
in the form /1 M99. Now the jump will be omitted or not, depending on the setting of the conditional
block skip switch.
