Hi Alex,

http://www.masmforum.com/board/index.php?topic=10252.msg125601#msg125601

not bad, Alex, not bad.

It doesn't seem to work on win7/64 bit system though.

[dedndave]

it's a 16-bit program, which isn't supported in 64-bit windows OS's
i think it can be done using DosBox or something

I think it's time to look forward. 16 bit world was funny, but only because we were young.
Thinking about all the limitations it had, it's much better to live in a 32/64 bit modern version.
:P

Frank,

:P

wise spoken, but we shouldn't forget some good tricks from the old 8 and 16 bit world.

Agreed. :t

[Magnum]

I agree with you.

We can just look at the code in some of our 32 bit programs.
