     In going from DOS 3.3 or ProDOS to standard MS-DOS, losing the Apple II
directory is probably unavoidable. Putting this another way: if you want
standard MS-DOS programs running on your PC to access the files, they will do
it under MS-DOS using MS-DOS's directories.

     It is fairly easy to convert Applesoft BASIC programs on a .dsk disk
image to Text. Running an Apple II emulator (like AppleWin) you add a line to
the program which LISTs it to a Text file. Here is an example (ref: David
Cross in the FAQs):

0 HOME:PRINT CHR$(4)"OPEN A2BAS.TXT": PRINT CHR$(4)"WRITE A2BAS.TXT":
  POKE 33,33: LIST 1,: PRINT CHR$(4)"CLOSE": END

RUNning the changed program creates a file on your disk image named
"A2BAS.TXT" which is a listing of the BASIC program.

     Possibly your method for moving files from disk image to MS-DOS will
also convert the Text file to PC format. (An alternative would be to use
ShrinkIt to create a .shk file of the Text. The .shk file could be moved from
the .dsk disk image to MS-DOS where Nulib could extract it and convert it to
a TEXT file named A2BAS.TXT in PC format.)

     Once you have an MS-DOS Text file in PC format, it can be edited by a PC
BASIC editor as necessary for running on the PC.
