The DATA Step Graphics
Interface (DSGI) enables you to create graphics output within the
DATA step or from within an SCL application. Through DSGI, you can
call the graphics routines used by
SAS/GRAPH to generate a custom graph, or to rescale and replay
existing graphs into viewports. DSGI GASK routines can be used to
query current system or graphics area settings.

about DSGI functions and routines, see The DATA Step Graphics Interface.
