The PostScript Language Reference Manual clearly states that if a
file is opened after a save, the corresponding restore will close the
file. What about the converse? If an open file is closed after a
save, does the restore reopen (and reposition??) the file?

The automatic closing of files by restore (and by garbage collection in Level 2) is merely a convenience. It ensures that the underlying file is not kept open artificially when it is no longer accessible at the PostScript language level. Ed Taft taft@adobe.com ...decwrl!adobe!taft
