For that you'll need to find an old copy of MS QuickBASIC 7 somewhere (4.5 might work depending on the language features you used).
That can compile your BASIC programs into DOS 16 bit executables.
And no, noone's going to point you to a download as it's not free software. It's a commercial product that's no longer be sold, but it's still protected under copyright and cannot be distributed.
As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.
