SYMPTOMS

The sample program shown in the More Information section below demonstrates a problem with the WINDOW OUTPUT n statement in interpreted programs. In the program, the PRINT and LINE output correctly appears the first time in window 1 (the current output window); however, after the INPUT statement is invoked, all subsequent output statements incorrectly go to window 2.

RESOLUTION

In compiled QuickBasic programs, PRINT and LINE output correctly goes to window 1.

To eliminate the problem, place another WINDOW OUTPUT 1 statement after the INPUT statement.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
