QBasic supports subroutines (called SUB for procedures and FUNCTION for functions). You can write very structured code with QBasic; pretty much the only thing it lacks is pointers, but it's a very capable language otherwise.

You can PEEK and POKE arbitrary memory addresses and use CALL ABSOLUTE to call assembly shell code at any address.
I remember typing out a mouse driver shell code in hexadecimal from a magazine. QBasic does not have built in mouse routines and the young me was baffled when you could make that happen with a long string of digits.
