Taking the Applesoft LIST routine will work.  You will just have to rip
out parts and change others.

As you follow along the code, $D6F7 is where one line gets detokenized
and output.  I'd take this code through to D765 and modify it to do what
you want.

You'll probably want to rip out the column-33-carriage-return-and-tab-5
bit at D705-D711, unless you want the "formatted" look in AppleWorks.
The exit part, D724-D72B, will also need to be changed to return to
AppleWorks.

BTW, does AppleWorks have ROM switched out?  If so, it needs to be
switched in so the token strings can be accessed at D731.

If you're always going to convert the whole program, you also don't need
any of the line-number range checks.
