Hello,
Yes, I've figured that much and I remember running into this problem before
but I can't remember if I was able to display the string in letters not the
ASCII codes or not. Because when I use {System.show Var}, I get the list of
ASCII codes while the result I need is for the string in letters to be
displayed.
Thanks.
