CONTOUR GEOMETRY (Cycle G37)
All subprograms that are superimposed to define the contour are
listed in Cycle G37 CONTOUR GEOMETRY.
U U U U Label numbers for the contour: Enter all label
numbers for the individual subprograms that are to be
superimposed to define the contour. Confirm every
label number with the ENT key. When you have
entered all numbers, conclude entry with the END
key.

Before programming, note the following:
Cycle G37 is DEF active which means that it becomes
effective as soon as it is defined in the part program.
You can list up to 12 subroutines (subcontours) in
Cycle G37.
