Title: Is it a bug or an attribute?
Post by: Petr on August 15, 2018, 02:13:20 pm

In the new IDE 07-21-2018 I noticed one thing. If I'm writing a program that uses multiple screens and I'm completing the compiled EXE file with CTRL + PAUSE, the EXE remain in memory and will not quit. I need to end it through the Task Manager. As an example, today's Direct Bitmap reader can serve. Open it in IDE, compile, run. If you hit CTRL + PAUSE when the BMP header is listed, this problem will occur. At that time, the program switches between SCREEN 0 and SCREEN _NEWIMAGE by the size it reads from the bitmap head.

That's some sort of race condition between the way SLEEP halts your program and the required changes the SCREEN statement will perform.

Replace SLEEP with:

Code: QB64: [Select]

1. k& = 0
2. DO UNTIL k&
3.     k& = _KEYHIT: _LIMIT 30
4. LOOP
