GOTO within M97?
Will the program get confused about where to flow, if I use a GOTO statement from within an M97 subroutine
within another M97 subroutine?
I have subroutine "B" within another subroutine "A".
Subroutine A is looping.
Subroutine B contains an "IF / THEN GOTO" statement
The IF statement basically says "if this is the last loop of A, exit the loop early."
The desired result is that only part of B will execute on the last loop.
A potential problem enters my mind. The M97 subroutine must exit without ever seeing an M99 code to end it. But then, I am going to call another M99 later. As far as the program knows, it is still in subroutine B, so it may want to return to A. But my GOTO statement has already gotten me out, and I've moved on. I want the next M99 call to return me to the main program. But I'm worried it may instead direct me back to wherever it left off in subroutine A.
If that's too confusing, try this: all I'm trying to do is break a loop and go all the way back to the main program. Like the movie Inception... I'm in a dream within a dream, and I want to just wake all the way up.
Here's a sample, using real numbers instead of A and B:
Code:
#1 = 0 (counter)
M97 P9000 L7
N9999
M97 P8000 (final action)
M84
M5
M30
N9000
#1 = #1 + 1
M97 P9010
M97 P9020
M97 P9030
M97 P9010
M97 P9021
M97 P9030
N9010
M51 (close clamps)
M61 (kill power to clamps)
M99
N9020
(do some moves)
[B]IF [#1 EQ 7] THEN GOTO 9999[/B]
(do some more moves that only apply to loops 1-6)
M99 [B](This is never reached on loop 7)[/B]
N9021
(do some more moves that only apply to loops 1-6)
M99
N9030
M52 (open clamps)
M62 (kill power to clamps)
M99
N8000
(do a final move)
M99
