James:

I know they're common from seeing their use in my own code, in code
written by others, and in questions posted to the PICLIST.

Personally, as I mentioned in my last public message to Clyde
Smith-Stubbs, I use them often enough that I've written a set of
MPASM macros to read, set, reset, toggle, and copy the states of
arbitrary bits in large bit-arrays.  An example macro invocation
looks like:

    SETBIT FLAGS,BITPOINTER

where FLAGS is the name of the register where the array of bits
starts, and BITPOINTER is the name of the register which points to
the bit you want to set.
