KW=>  I am trying to use binary for the first time.  I run this program and

    Thanks!  -Keith

        When you PUT  #1,,string, QuickBASIC write  only the characters  in
the string.  If you  plan to  used variable-lenght  strings, you  must also
write the lenght of the string. Use the following sentences:

TEMP$=MKI$(LEN(string))+string:PUT #1,,TEMP$
        or
TEMP%=LEN(string):PUT #1,,TEMP%:PUT #1,,string
        These two lines will save the lenght of the string and then all the
characters in the string.

string=INPUT$(CVI(INPUT$(2,filenum)),filenum)
        This will read the string back into a string variable.
