I need help reversing a string

-----------------------------------

What is it you are trying to achieve?
I'm trying to reverse a string


What is the problem you are having?
I err... can't do it.

If I have var teststring : string := "testmebro" how do I get put teststring to ouput "orbemtset" 

This is vital to an important conversion program that I have to do. I can get it to convert 222 and other palindromes, but when it tries to convert 2A it gives me the answer for A2 and vice versa.

The sooner I can do this the sooner I can get started on GUI and binary. Any help is incredibly appreciated.

reverse for loop saving the individual characters in an array?

var name : string := "Lucas"
var backwards : array 1.. length (name) of string

for decreasing a : length (name) .. 1
   backwards (a) := name (a)
   put backwards (a) 
end for

lucas, you could make it even simpler and get rid of the array

var name : string := "Lucas" 

for decreasing a : length (name) .. 1 
put name (a)
end for

Also, by adding a couple of period characters at the end of the put line, it will keep them all on the same line.
put name (a) ..

Wasn't specified. Typically these small programs don't have much of a need to save the text outputted, and just display the text. If saving is going to be included, one could either save the lines into a flexible array and put them in afterwards, or put each line in the text file in the for loop itself.

Has anyone considered saving it as a new string variable? :P

var name : string := "Lucas"
var backwards : string := ""

for decreasing i : length (name) .. 1 
    backwards += name(i)
end for

put backwards
