    Here's the code again, just in case it was bad(might of been a comm
error or something).

    It would be rather easy to fade the other way- from dark to bright.
I should of included a subroutine to do that(only a couple of
modifications would be required)...

    If you need this type of fade, let me know and I'll post it!

'****PART 1****
'The following program makes the fade.obj file. To make a .QLB use:
'link /q fade,fade,,bqlb45.lib
'(assuming bqlb45.lib is in the current directory)
'To make a .LIB so you can compile it, enter LIB at the DOS prompt and
'fade.lib  at the library prompt
'Y         at the "Make new library?" prompt
'+fade.obj at the operations prompt
'<Enter>   at the listing prompt

OPEN "fade.obj" FOR BINARY AS #1
S$ = "": Check = &HFFFF: CheckSum = 0
FOR A = 1 TO 345
    READ A$
    A$ = "&H" + A$: V = VAL(A$): S$ = S$ + CHR$(V)
    Check = Check XOR V: CheckSum = (CheckSum + V) AND &HFF

IF Check <> &HFF3F OR CheckSum <> 0 THEN
    PRINT "UNcool! This copy has been trashed!"
    PRINT "Success!"
    PRINT "R.G."
    PUT #1, , S$

P.S. I just tried this program out and it works fine. Thank god I used
some error checking!
