Pretty cool.  However, won't it break if the strings are longer than 256
bytes total since then they could overlap a page?  At least that used to be
a problem with the PIC16F series.

I tried this:

M_1="\nThreadSize is %s\n"
M_2="ThreadDepth is %s\n"
M_3="ThreadArea is %s\n"

Result was:

Optimization saved 0 characters from being duplicated

Most of my strings are literals used in printf statements

Still, it bears looking into.

Thanks.
