Be a little bit careful here ....

the original script you posted (i.e. using replace) will replace the 
string "Piper" with "Jones" - regardless of whether it is an entire word 
on its own or not.
so "abc Piper def" would become "abc Jones def", but also "abc 
ghiPiperjkl def" would become "abc ghiJonesjkl def".

However, using wordoffset as described here will replace the entire 
word, so "abc ghiPiperjkl def" would become "abc jones def" !!

If you only want to replace Piper when it is the entire word, you can 
set  wholeMatches (q.v.) true to get around this.

If not, then you might instead do
   put offset("Piper", tContainer) into tStart
   put "Jones" into char tStart to tStart+4 of tContainer

-- Alex.
   put "Jones" into char (charoffset
