If this is what you're looking for, I am currently writing a set of programs
that convert a text file BASIC listing to a runnable form or a runnable
BASIC program to ASCII text.  It's not completely finished (I don't have it
working for screen control characters yet), but its getting there.  

The good (or bad) news about it is that am writing it in C for Unix and
Amiga machines.  I just acquired a C64 emulator for my Amiga and wanted to
be able to write programs for my SX-64 on my Amiga (because I can no longer
stand to use the C64 screen editor).  I'll post or mail you a copy of the
source code (probably post if enough people are interested, besides, my
mailer is flakey) when I get it complete.

If you can't wait (and if you are looking for code that doesn't run on the
C64 itself, if you are this wont help you), all I did was write lex routines
that read in each token and convert it to ASCII.  In the reverse, it just
reads in the keywords and outputs the tokens.  I put all text in lower case
letters so that it will be distinguished from BASIC keywords.  For screen
control characters, I created tokens like <GRN> and <CRSR_DOWN> to encode
them in ASCII.  The only really hard part was writing a routine that encodes
the line numbers because they are in binary and have pointers to the next
line number in memory.  This was easy on the BASIC-ASCII but quite hard on
the ASCII-BASIC.
