1. 1

    The most important aspect of developing an app is the compiler toolchain. For this, we have the Visual C++ 1.52.

    The app is very impressive, but I wonder if the choice of dev environment here made the work harder than it needed to be? There were better development environments available for Windows 3.1.

    I would have picked Delphi. It even had the, then revolutionary, concept of a debugger that could catch exceptions causing GPFs. I was not at that demo, but have heard from those who were there how that was greeted. Great UI tools too.
