Note: In Incremental, Trig Help cannot be used as each point is related to the current position.

Trig Help can be shut off by setting bit 2 of the miscellaneous special flags parameter.

This may be desirable for programs generated from some Cad/Cam systems.

Corner rounding (,R)

By adding ,R___ to the end of blocks commanding linear or circular interpolation, corner

rounding can be automatically inserted.
