Where can I get a list of commands for Qbasic for Windows?
Qbasic for Windows doesn't have a set of commands. It's actually a mini-IDE where you can enter Qbasic programming language to create programs.
You'll have to Google the QBasic language to see exactly what are the instructions that you have to use.
