Thank you for that. Perhaps the help is misleading. It says
"the following general rules apply:
- For string comparisons, case-sensitivity is controlled via the respective setting of the value range expression that is used as comparison parameter.
- As opposed to the previous rule, pattern matching comparisons are performed case-insensitive."
It appears to be talking about string comparisons in general. The most common place we do these is in a rule. Very rarely do we bother using the value range expression. Because I was thinking the quoted help was talking about string comparisons in rules I was confused by the reference to the value range parameter. I now see (as you pointed out) that the passage is talking only about the Value Range expression.
Thanks
