Information
Modal G functions can be changed in the subroutine, e.g. G90 –> G91. When returning to
the calling program, ensure that all modal functions are set the way you need them to be.
Please make sure that the values of your arithmetic parameters used in upper program lev-
els are not inadvertently changed in lower program levels.
