Description

PSPLC specifies the color of a polyline. Depending on the edit mode, this function either inserts the new structure element directly after the element indicated by the pointer or replaces the element indicated the pointer. The pointer then points to the new set polyline color element.

If Digital PHIGS is in immediate mode, it performs this function immediately, but the function does not create a structure element. If CTYPE = PINDIR, the function uses the COLI argument. Otherwise, the function uses the COLR argument.

The new function syntax conforms to the ISO Fortran standard. Digital recommends that you code using the new function syntax.
