Well, you could use the same trick that the postscript text-printing
programs use.  If a postscript program reads from its standard input,
the text comes from the file that's being printed.  Your files could
look like this:

/interpreter {...} def
interpreter
... encoded bytes ...

Where the {...} is code that reads the encoded bytes from the standard
input and draws the appropriate lines.  For an example, see the
Postscript cookbook or any of the Postscript text-printing programs.
