GSHOW Call

CALL GSHOW( <segment-name> ) ;

The GSHOW subroutine is a graphical call that displays a window. If you do not specify segment-name, the GSHOW subroutine displays the current graph.

If the current graph is active at the time that the GSHOW subroutine is called, it remains active after the call; that is, graphics primitives can still be added to the segment. On the other hand, if you specify segment-name, the GSHOW subroutine closes any active graphics segment, searches the current catalog for a segment with the given name, and then displays that graph. Examples of valid statements follow:

call gshow;
call gshow("plot_a5");

seg = {myplot};
call gshow(seg);

See Chapter 15 for examples that use the GSHOW subroutine.
