Microsoft BASIC PDS 7.1 User Interface Toolbox

[a740g]

This was supposed to go in the Museum a long time ago. However, I never got to re-implementing the assembler routines that this uses... until now.
I've included the assembly sources as comments in General.bas. Below those comments you can find the QB64 function ports.

From MS PDS 7.1 Getting Started docs:

User Interface Toolbox

With the new user interface code samples, you can design your own user interface using
BASIC procedures. The code samples in this toolbox give you complete control of character-
based window interfaces. For example, you could write a BASIC program with multiple
windows, menu bars, dialog boxes, and mouse interaction. For more information about the User
Interface toolbox, see Part 3 of the BASIC Language Reference.

Please note that this is by no means a perfect port. There are a few differences and quirks.

Happy tinkering!
