If the example you give is an accurate portrayal of what you are trying to do,
why not just:
set the backcolor of char 1 of word 2 of line 3 of temp to "red"??

You're right Ben - your general approach can be combined with my (simple
minded) approach, and a few simple checks thrown in to give us a general

like "token 3 of word 2 to 4 of line 3 to 7" ...)

Hi Alex,
Yes that's that approach I was trying to make a relatively general version of
(see my response 16:50) to handle arbitrarily complex chunk expressions - but
it would still fail (in fact probably worse?) with chunk 1. But I think the
principle is right.

Not quite so straightforward, but you can do
function getCharIndexByLineToken pVar, pLine, pToken
local temp
put the number of chars in line 1 to (pLine-1) of pVar into temp
add 1 to temp -- for the CR between lines 14 and 15 !!
add the number of chars in token 1 to (pToken-1) of line
Sorry to be so dense but can you colorize text without a field? Or are you
running through the text as an XML tree (either Rev's or your own) or
manually editing HTML text behind the scenes and adding a colorization
attribute?

Thanks for all the suggestions. Need some time to try them out. I really like
Thierrys RegEx approach and the others look promissing too.

For those whose eyes glaze over when looking at regexp, it seems Jacque's
suggestion of the offset function making use of the chars to skip easily
solves this problem. I don;t have the original post in front of me so
can't remember if the objective was to find the last occurrence of the
character
Here's a function I use all the time, which may come in handy:
function offsets str, pContainer
-- returns a comma-delimited list of all the offsets of str in pContainer
-- returns 0 if not found
-- note: offsets("xx","xx") returns "1,3,5" not "1,2,3,4,5"
-- ie, overlapping of

Hi all,
thanks for
Will the offset function work?
put the number of chars in line 1 to 14 of tVar into tCount
put offset(startChar, line 15 of tVar) + tCount into tStart
put offset(endChar, line 15 of tVar) + tCount into tEnd

Hi all,
thanks for the replies so far.
The problem with both matchChunk and offset are, that they will return the
first occurance of the literal. So in a text like this:
orange banana tomato
banana tomato orange
tomato banana orange
on mouseUp
local temp,tChar
put fld 1 into temp
put

Hi Malte,
If using a field is the only solution, try the

Best I could do is:
*on* mouseUp
*local* tVar, tStart, tEnd
*put* fld "fData" into tVar
*get* matchChunk(tVar, "(" & word 8 of tVar & ")", tStart, tEnd)
*answer* tStart & comma && tEnd
*end* mouseUp

Hi all,
I need to find the start and end character of chuncks in a variable. If we are
in a field we can use charIndex for that. However, in a variable I have no good
idea on how to do something similar to
get charIndex(token 7 of line 15 of field „myField“)
Any ideas?
All the best,
Malte
