You know (for what it's worth), IBM did release VisualAge Basic for OS/2!
Let me know if you want it, I have 1.27 release of this thing, circa 1996...but hey, nice VisualAge GUI would certainly halp.
BTW - I did actually have this installed on one of my OS/2 boxes as my son wanted to "figure out this programming thing"....lol, he was just starting up, and for those of us who similarly cut our teeth on BASIC I couldn't think of a better way to get him going...
