GetMessage

[James C. Fuller]

I did a quick search here and on the PowerBASIC board and found most source code does not check for an error condition when calling GetMessage.

Any particular reason for the omission?

Nothing, excepting that it is seldom needed. With PB, returning -1 should only happen if the hWnd parameter is invalid, but you should have stopped the program before if you check the result of CreateWindowEx.
