What is this "VA_START" message?

The operating system and other programs communicate via "messages": If, for instance, you called this page with a mouse-click, the operating system has sent a message to the display program, informing it that "the left mouse button has been pressed".

A program already in memory can be requested via "VA_START" to load a file. If you are interested, you can read more about this message and the AV_Protocol in the GEMINI (alternative) desktop manual.

What does "WDIALOG.PRG" do?

WDIALOG is a compact system extension which, apart from window dialogs, popups and listboxes, also contains a comprehensive selection of fonts. These functions are integrated into the multitasking system MagiC since version 4.

WDIALOG allows users of older operating systems access to these features. COPS isn't the only program which uses WDIALOG - the NVDI tools "FONTNAME" and "MAKEPRN", the spreadsheet program "Texel" and also "ArtWorx" make use of WDIALOG functions.
