I was lacking bitwise operators in a few dialects when I created the Terraspin program for the BASIC Month challenge that I did back in July. The only operators I needed were AND, right shift, and checking to see if the lowest bit was set. Right shift was easy to simulate, just divide by two. Checking the lowest bit was done with divide, multiply, and subtract in a user defined function. The AND required a loop.

The routines are in the source here and fully commented:
