Maintaining metafiles (plots generated by GPLOT):
To save the graph in an enhanced metafile, enter specification
OUTFILE=<name_of_metafile> (default extension .EMF)
To plot over another plot saved earlier by the OUTFILE option, enter
specification INFILE=<name_of_metafile>.
Pictures can be accumulated by using the same metafile in
INFILE and OUTFILE specifications.
To display metafiles generated by Survo, use the GPLOT FILE operation.
