Depending on what you're doing...you might get away with using mathematical operators to accomplish the above... A right SHIFT would be dividing by 2. A left shift would be multiplying by 2. I don't know off the top of my head about AND and OR. Doesn't the manual cover this? -Ken

Not operators, but better than nothing :) Anyone interested, please feel free to email in private. In fact, the lib is simple as a moo. -- ������������������
