GSHOW Call

shows a graph

CALL GSHOW <(segment-name)>;

where segment-name is a character matrix or literal specifying a graphics segment.

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);
