Hi to all,

There is a lesson called "Reversing text" in the LiveCode developers area. It's here: http://lessons.runrev.com/s/lessons/m/2 ... rsing-text
When I follow this lesson, I don't get at all the expected result, and I don't understand why... The reverse text isn't done.
I have the fields "Reversed Text" and "Answer", and a button with the code from the lesson:

Code: Select all

on mouseUp
   get reversed("A man, a canal, Panama")
   put reversed(it) into field "Reversed Text"
   answer reversed(field "Answer")
end mouseUp

And the function reversed() is in the card:

Code: Select all

function reversed pString
    local tReversedString
    repeat with tChar = the length of pString down to 1
        put char tChar of pString after tReversedString
    end repeat    
    return tReversedString
end reversed

Are they some of you who have done this tutorial with sucess ?

Note: I use LC 6.5.2

Thanks in advance.

Hi Atout66,

Yes reversed function works well but your script reverse the string two times.

Code: Select all

on mouseUp
   get reversed("A man, a canal, Panama") -- you put the reversed string in it
-- put reversed(it) into field "Reversed Text" -- you reverse it 
put it into field "Reversed Text"
 --  answer reversed(field "Answer")
end mouseUp

Sorry I don't understand

Code: Select all

answer reversed(field "Answer")

I guess

Code: Select all

on mouseUp
 ask "String to reverse"
   if it <> empty then
      answer reversed(it)
   end if
end mouseUp

Best regards
Jean-Marc

Ah ! you're right Jean-Marc. I was confused with this script from the lesson. I understand why now

Still don't guess what the teacher meant with:

Code: Select all

put reversed(it) into field "Reversed Text"
answer reversed(field "Answer")

instead of

Code: Select all

put IT into field "Reversed Text"

only...

Anyway, thanks for your help

Hi guys,

at the top of that namely lesson, like in many other lessons,
the author just shows a couple of exmples of the usage of his function:

...
get reversed("A man, a canal, Panama")
put reversed(it) into field "Reversed Text"
answer reversed(field "Answer")
...

They do not neccessarily have any further meaning

Best

Klaus

That's exactly what I misunderstood Klaus
