-> There's a very specific reason that the code I posted doesn't use
-> delimiters:  The LCD displays that are the subject of this thread use

Thanks for your comments Andy. Actually, both techniques (strings
proceeded by a size byte, as used by DOS, and delimited strings) are
valid and have been used since the beginning of computing itself. Each
has its advantages and disadvantages. Both require a table read, an
index advance, a compare, and loop for each value. Both can be used to
concatenate strings together by two CALLS if the DISPLAY routine returns
the pre-advanced index in W.

However, the delimited method allows trailing substrings to be
transmitted so long as at least one value out of 256 is available as
EOS.

The sized approach has the advantage that leading substrings may be
transmitted if the DISPLAY routine has a second entry point (after size
byte read) and the caller preloads the size before calling DISPLAY.

I tend to use delimited strings for text, but have also used sized
strings (even in C!) when dealing with binary communications.

BTW thank you for your efforts to resolve the interrupts during ADDWF
PCL issue.
