I am trying to write a function that does search and replace of strings in
a stack.
     
Basically, it is a function of the form
replace "wordToFind","howToLook","replaceWithThis"
     
Once entered into the message box, the the function begins to work, but
after a number of times, it stops with a too much recursion error. Does
anyone have an idea why?
     
Internally, the function puts the wordToFind and ReplaceWithThis into
global variables then proceeds to find wordToFind. It then gets the position
of this wordToFind in a field that the find command found it in by using
the foundchunk. It replaces the wordToFind that is in the field at that
location, then proceeds by calling finding again recursively.
     
It may be that the calling of find is being nested many times. Is there
any way to make act as if it were being called fresh each time?
     
     
Thanks a lot for any help.
Maurice
