In a stack I have two fields :
One, « towns » is a list of towns where when a line is clisked, I
put the
name of the town in « tthisTown »
The other field « statClients», is a big list each line of which
includes
a
number of items separated with tab ; the first item being the town.
I wish to get in a third field, say « results », only the lines
concerning
the clicked town.
How about using the filter command?
ON mouseUp
local tThisTown, tStatClients
lock screen
put value(the selectedLine) into tThisTown
put fld "statClients" into tStatClients
filter tStatClient with "*" & tThisTown & "*"
put tStatClient into fld "results"
END mouseUp
The *'s at the start & end of the filter string mean that your town
can occur anywhere in the line, not just at the beginning or end.
Cheers,
Sarah

I was just going to post a filter command might be the most useful
here,
but just for reference, your results field was not being populated
because
you were using an "exit mouse up" to end the repeat loop when the
find
result was "not found". Therefore your list was being built up line
by
line with each find, but then the handler was exited after the last
one,
without being able to do anything with the results.
In those circumstances a REPEAT UNTIL (result is "not found") or
REPEAT
WHILE (result <> "not found) type structure would be better. (You
could also
use "exit repeat" in the if statement, rather than "exit mouseup"
but a
conditional loop is probably neater.)
Ooops ! YES ! very happy to eventually understand my mistake ;-))
Of course, you are right, exit repeat, not mouseUp.!
Anyway, I think I shall adopt the filter command
Thanks a lot for your attention and your revision
Best regards from Grenoble
