From Rosetta Code, I was able to translate a Maze generation routine from a QB64 for Locomotive BASIC.
The original code produced a 40x20 maze and recommended using even numbers for the Width and Height.
I have set it up for MODE 1, 38 x 20 and it actually takes a while to prepare, though it should be useful for creating maze style games as it requires very little information to adjust for MODE 0.
