I am quite sure you would need QuickBasic proper for that, however I don't have the manual around to confirm that.

QBASIC had the CALL ABSOLUTE statement for calling machine language code. It didn’t require QuickBasic, the QBASIC that can with MS-DOS had it. Also GW-BASIC had it before it. You store the machine code as a list of integers in a DATA statement.

If I remember correctly, you had to run qbasic.exe with a /L switch to load 3rd party library.
