How many table entries are there?  Unless the table is very small, a normal
table will be more compact than what you did above.  Are you totally out of
room or just room in the first 256 locations?

What volume will you be producing these in?  If the volumes are small, then
just getting a bigger PIC for an extra dollar or two will be much cheaper
than spending a lot of time trying to squeeze twenty pounds of code into a
ten pound PIC.
