running QB45

[allan1952]

I just installed vDOS (version 2021.05.01).  I want to use it to run Quick BASIC 4.5.  Dir structure is C:\vDOS\QB45

Installation seemed to go OK.  I start vDOS and get a command line.  Then I start Quick BASIS by typing qb (I don't recall there ever being a batch file). 

The Quick BASIC screen appears but it's frozen.  It accepts no keyboard or mouse commands.  And I have to close the window using Task Manager.

Does anyone know what I'm doing wrong?  Please help.  Thank you.

QB programs should run w/o problems. The QB IDE however uses INT9/IRQ1 to communicate with the keyboard.
vDos doesn’t support that low level interface, so the IDE won’t notice any keypresses.
You have to uncomment the line “rem MOUSE = ON” in config.txt for the mouse to work.

For QB program development by the IDE you essentially have to use DOSBox or one of its mods.
