Hi all

Im stuck on a bit of code and looking for a bit of help.
I need (i think) a for loop to analyse a string and remove all non alpha characters from it.

Something like:
Input text "today is my 21st birthday"
result "todayismustbirthday"

I assume Id need a loop to look at each character starting at index 0 and steping by 1 each time.
The loop would then take the value of all the characters (alpha) and write them to a result string.

Can anyone help?

thanks
