Example of R parameter transfer
N10 G0 X0 Y0 G90 T1
N20 R10=10 R11=20
N30 RECTANGLE
N40 G0 X50 Y50 G90
N50 RECTANGLE
N60 M30
Calling main program as subprogram
A main program can also be called as a subprogram. The end of program set in the main
program M30 is evaluated as M17 in this case (end of program with return to calling
program). You program the call specifying the program name. Example: N10 MPF739 or
N10 WELLE3
A subprogram can also be started as a main program.
