Thanks for your reply!
That doesn't seem to work in my situation, because I'm looping through positions in an array, so there is no place where I can insert the lowercase() expression.
My code is like this:
myArray For each X element
--myArray currentValue ="a"
I also don't want to permanently manipulate the contents of the array (I need to retain the mixed case letters, just not for the comparison).
Damn.. this is more difficult than I thought. I wonder why =equal to "a"|"A" is not working.
