How do I check (or set) a group of consecutive bits within a byte?

[Charlie]

Check page 78 of the PBP3 manual - it talks about 'BITWISE AND' (expressed as '&') which is what I think you are looking for.

I haven't been brave (or dumb?) enough to use it yet, but it seems to be there.

Unless you're not using version 3, in which case, please excuse the interruption.

I'm using 2.6 and it's not in my manual.
