    This should (hopefully) be real simple. First, go to gwbasic and
load in your program. Then, save your program like this:

SAVE "program.bas", A

    The "A" is very important. Normally, gw-basic encodes all of it's
reserved words(such as PRINT, GOTO, INPUT, etc.) with one byte tokens.
QuickBASIC has a heart-failure over them. The ", A" at the end of the
save tells gwbasic to save the program in ASCII form, or in a raw text
format. After that is completed, you should be able to load in the
program you saved in ASCII form into QuickBASIC without any problems.

    You still might have problems though. Some gw-basic structures are
not valid in QuickBASIC. Here's one of them that will work in GW just
fine but will not work in QB:

10 For A=1 to 20:if Array(A)<>2 then next else print "Found at ";A

    This will cause QB to say "Next Without For Error". To correct this,
you would have to rewrite the code(which sometimes is more trouble than
it is worth). The above line would be rewrote like this:

For A=1 to 20
    if Array(A)=2 then
         exit for
if Found then
    print "Found at ";A

Hope that helps!! (if your converting simple gw-basic programs then you
probably won't have to worry about the for/next thing).
