Oh, yeah, I forgot to say why just printf'ing won't work.  I've got 40
different messages to print, some have numbers in them, some display the
time, some display temperatures, some don't.  It would be simple if they
were all like:

"10:01 AM System ON"

But some of them are also like:

"Soup Temperature 24510F" or
"Error! You Bozo, shut off the power!"   or
"Call 1-800-IMA-DUMMY for help"         and so on.  *

That's why I am thinking that concatenating a string would be the right
approach.  So far my efforts with STRCAT have produced nil for output.  For
instance the simple code:

 DO{
     puts(*string1);

     delay_ms(1000);

     strcpy(string2, "A");
     strcat(*string1, *string2);      // concatenate string1 and 'A'

 }WHILE(TRUE);

which I imagined might print "A" then "AA" then "AAA"  then "AAAA" etc just
prints a CR-LF over and over.  Phooey.

*Humor content of messages has been increased to add interest.  Real
messages are not this funny.
