Right, "replace" is the thing to use for a global replace task, but if
you are doing a more sophisticated search/replace -- checking context
of various matches and narrowing the search further -- the multiple
offsets function is quite useful. Also, I need on occasion to find the
*last* occurrence of a string in a container, and "item -1 of
offsets(tString,tContainer)" is great for this.

Peter,
As David pointed out, you can do that easily with the replace
command. I thought I'll mention this to avoid confusion.

The code above will find and replace the first occurrence of the
string. For access to all the occurrences, use this handler:
function offsets str,cntr
-- returns a comma-delimited list
-- of all the offsets of str in cntr
if str is not in cntr then return 0
put "" into offsetList
put 0 into startPoint
repeat
put offset(str,cntr,startPoint) into thisOffset
if thisOffset = 0 then exit repeat
add thisOffset to startPoint
put startPoint & comma after offsetList
end repeat
delete last char of offsetList
return offsetList
end offsets
