Parameters for subroutines without values
In the case of subroutines without values, the current data are transferred by means of para-
meters R00 to R99.
These parameters are used in the subroutine instead of numerical data.
A maximum of 10 parameters can be programmed in each block.
When the subroutine is called the parameters used must have the correct values.
Values are assigned to the parameters in the main program.
Example:
R8=
140
R6=
120
The contour to be cut is stored in a subroutine.
