Hi David, This section of the Language Reference may help in remembering which operand (of the equality operator) gets the wildcard.
It’s found in “Operators” -> “Comparison Operators”. Then look for section titled "More about string comparisons”. For wildcard placement: "The wildcard character must be used within the second operand (the string on the right side) in order to match any number of characters.” See: http://doc.4d.com/4Dv16/4D/16/Comparison-Operators.300-3036456.en.html#Paragraph_863680 Best regards, Jeremy French > On Jan 23, 2017, at 10:00 PM, David Adams <[email protected]> wrote: > > This is probably documented, long-standing behavior that everyone but me > knows and remembers.
