Hello
 I have  Mach 3 with license but still 1000 subrutines limit ? what should I do ?
Please Help

make subroutine call subroutine, for example one million calls (1000x1000):

M98 P1 L1000 (call from main program)
M30

O1 (sub that calls sub)
M98 P2 L1000
M99

O2 (sub that does the work)
... do work here...
M99

Basically, yes, there is a limit.
Mach3 cannot handle a huge number of nested subroutines. It starts to lose variables. You have to keep the number of SRs down. Sad, but so.

Cheers
Roger
