Case-sensitive Position() function

Sample Input:
Sample Output:

(Strangely enough, this is NOT normal in FMP7!)

 Then copy & paste into FileMaker Advanced's Edit Custom Function window.


For the average user, it is quite hard to understand why FileMaker made some functions and ScriptSteps case insensitive. It is very easy to render a function case- insensitive by using the uppercase() or lowercase() functions on the text argument, but is rather complicated or sometimes even impossible to render a function Case-senSiTiVe. This wrecks most of my FMP6 solutions in FMP7.

One of the most vital functions is Position(). Another is PatternCount().

Position("ABCDEabcde";"a";1;1) used to result in 6 in FileMaker 6, and now returns 1(as in Position(lowercase("ABCDEabcde";1;1)).

PatternCount("Aa";"a") gives 2 instead of 1.

The functions above will not work if the marker string is already found in the text

Use the enhanced function for encoding, (as in MagicEncoder or ASCII Coder) or to highlight text CaSEsensiTIVEly.


Note: these functions are not guaranteed or supported by Please contact the individual developer with any questions or problems.
