Actually, that is the same program I used. I referred to it mistakenly as VBDis.

I used it to recreate the VB3 "pseudo source" files. I say that because VB4 was not able to open them. VB4 being the successor to VB3 should have been able to open a prior version. To be more specific, VBDecomp recreated:

<prog>.1
<prog>.2
<prog>.3
<prog>.frm
<prog>.mak
<prog>.bas

And a few others....

Appreciate your responses!
