    	I remember using Visual Basic for Windows, but not the DOS version. I’d have to look at the version though. I remember buying it at Egghead Software across from my office in NYC.

program based on the COW library. Does anyone have/know of a sample program that used the library? Was there an SDK for it or was it used only for Microsoft's products?
Reading this just reminded me of Visual Basic for MSDOS, which had a windowing system for the 80x25 IBM monochrome
adapter. I purchased it in 1992 but didn't use it very much, but I just dug it out of the back of a cupboard for a look.
One of the manuals says "Visual Basic provides a complete development environment for MS-DOS applications. You can
design the windows, dialog boxes, menus, command buttons, option buttons and other interface elements for a application."

Visual Basic for MSDOS was compatible with QBasic and QuickBasic and even had a forms designer. The diagrams of the
character UI screens in it are very similar visually to Windows 2, they sure made heavy use of the box drawing characters.
