 Visual Age - an IBM product, this means...

 1 - You can only write applications for OS2 or IBM related O/S
 2 - Only IBM supported database engines are allowed, i.e: DB2
 3 - Poor product documentation and no 3rd party books.

 Good Luck! :)

 Visual Age C/C++, does have a very powerfull compiler, but the GUI
 design tools they can - I`d rather not say..... A very nice tool
 to develop system DLL`s and stuff with, but don`t try to write
 a GUI application. Your learning curve for this compiler is about
 6 months to 1.3 years.

 Visual Age Basic, don`t even bother looking at it! It does have
 compatability with Visual Basic V3 applications, but 90% of your
 programs will not work. It claims to have compatability with
 Windows 95/NT, but I never saw anything work. Another nice
 feature to mention is that it likes to crash OS2 while you are
 editing. And it is well known as a slowdown tool. Applications
 require at least 90 seconds to start up.

 In conclusion - both products require at least 16meg of memory
 and this means that your distribution applications also require
 machines with 16meg, but don`t worry: it`s not documented anywhere!
 With the exception of Visual Age C/C++, since you control memory
 allocations.

 Your options:

 1. You can either consider writing an OS2 application in Visual Age
 C/C++ using resource editors, and that crap, taking you at least
 5 months.

 2. You can evaluate another compiler, so far the best compiler for
 OS2 I have ever seen is Speed Pascal, it`s brilliant! Pitty IBM
 does not learn from these people.

 3. Consider writing your applications for Windows.

Kajoko!
