building a dynamic var [Solved]

Hi to all,
There is something I'm missing with the construction of a dynamic var.
Look the code below:
Code: Select all
put "2" into lItem
put "0" into les1
put "0" into les2
put "0" into les3
repeat with zzz = 1 to 3 -- just a test
put "les"&zzz into leTest -- build <les2> for example
if last char of leTest is lItem then
add 1 to leTest-- ERROR ! LC suggess leTest is numeric? and it is in that case
I also tried without the quotes like:
but it doesn't help...
Thanks in advance if someone has an idea
Regards, Jean-Paul.

Bonjour Jean-Paul,
in case like these you need to:
1. use an array!
Code: Select all
...
## Hint: No need to QUOTE numbers!
put 2 into lItem
put 0 into tArray["les1"]
put 0 into tArray["les2"]
put 0 into tArray["les3"]
repeat with zzz = 1 to 3
put "les"&zzz into leTest
if last char of leTest = lItem then
add 1 to tArray[leTest]
end if
end repet
...
2. DO IT!
...
do ("add 1 to" && leTest)
...
Best
Klaus

Ah, that's clever an array, I got it;-)
Thanks Klaus,

Hi Jean-Paul - I think the problem is that you are trying to do a mathematical process on a string - leTest is a string and therefore the last char of it will be a string (even though it's a number!). If you were to separate it out, as in "put the last char of leTest into tVar" then tVar could be interpreted separately by the engine as a number - and then you could do maths stuff with it...
But in my example I haven't bothered with that as zzz already holds the number we need...
Code: Select all
on mouseUp
put "2" into tItem
put "0" into les1
put "0" into les2
put "0" into les3
repeat with zzz = 1 to 3 -- just a test
put "les" & zzz into leTest -- build <les2> for example
if zzz = tItem then replace (the last char of leTest) with (zzz + 1) in leTest
end repeat
end mouseUp
EDIT 1: Aha speedy Klaus strikes again
- I got distracted responding to this and got pipped-to-the-post!
EDIT 2: and I see that you were after something different to what I thought you wanted - so Klaus is doubly right and an array should be great for you...

Thanks to all of you, I realized how to deal with strings and numeric value
