Terminate the strings with the \0 character and you only need the starting
address.  Then make a table of defined strings ie.

HELLO is the pointer to the string "Hello\0"  HELLO is only one byte, and
makes your code readable vs. 2 bytes per displayable character using in
16CXX type tables; A big mess vs:

movf LINE1,w    ;move cursor
call lcd_goto   ;to home

movf HELLO,w    ;display
call disp_str   ;hello string

:disp_str
call gets_i2c   ;get and
call lcd_puts   ;display

... and so on

Has anyone built a cheap easy serial memory programmer I can use with MPLAB?
It would sure be nice to dump a hex file out to memory device using ICSP.
