The objreplace subroutine positions the editing pointer at the location specified by the tag parameter. All subsequent graphics primitives overwrite the display list at the current location of the editing pointer. In general, no two dissimilar GL subroutines are the same length. The objreplace subroutine is best used for changing the parameter values of a subroutine that has already been compiled into a display list. Use the objdelete and objinsert subroutines for more general replacement.
Parameter tag Specifies a tag within the object definition to be edited.
