repeat with if

Hi,
I need a loop (with many lines of code inside) acting in ascending or descending order depending on the state of an external button.
How do I do it without creating two loops duplicating all the code?... ie acting only on the head?
Something like this does not seem to work:
-------------
on mouseUp
if not the hilite of button "reverse" then repeat with a = 1 to 200
if the hilite of button "reverse" then repeat with a = 200 down to 1
## code
end repeat -- ???
end repeat -- ???
end mouseUp
-------------
Thank you

Hola Fermin,
you cannot nest the loops this way
If I understood your problem correctly, this should do it:
Code: Select all
on mouseUp
if the hilite of btn "reverse" then
repeat with a = 200 down to 1
## do your reverse repeat stuff here...
end repeat
else
repeat with a = 1 to 200
## do your repeat stuff here...
end repeat
end if
end mouseUp
Best
Klaus

Well, one quick way:
Code: Select all
on mouseUp
get the hilite of me button "reverse"
if IT is true then
repeat with a = 1 to 20
yourcode a
end repeat
else
repeat with a = 20 down to 1
yourcode a
end repeat
end if
end mouseUp
on yourcode a
# ...
end yourcode
HTH,
Thierry

Hallo Klaus,
Once again you're faster

Thanks, Thierry and Klaus, but the inner code is the same in both cases. I do not want to repeat it. I would like to work by changing just the first line.
[Repeat with a = 1 to 200] vs [repeat with a = 200 down to 1]
... but it may not be possible.

well, putting the inner code in a handler,
then you have only one time your code!
And don't worry, it's fast
Or what did I miss?

Good idea, but the handler must to have many local/global variables ...
I think I've found a solution that seems to serve:
Code: Select all
on mouseup
-- the main variable is 'a'
repeat with b = 1 to 200
put b into a -- normal mode
if the hilite of button "reverse" then put 200-b into a -- reverse mode
-- here the code related with variable 'a'
end repeat
end mouseup
Thank you very much

If the script produces any kind of list, it might be possible to run the handler normally and then reverse sort the list after the loop completes if the Reverse button is hilited.
