Hmmmmm!  Pity!  I was hoping fsr would be, by default, loaded with the
address of the last accessed variable, but I'm obviously off the track.
Ah well.  My reason for this attempt was that I could, in development,
name the first address of the set of addresses, and access them as
shown, sometimes in several places in the program.  Then, if I needed to
change the location of the set of addresses for some reason (conflict
with another set), all I had to do was change the address assigned to
the variable in the cblock command.
Thanks all for replying
Howard.
