This limit can now be increased or decreased using SetRecursion. No more 10K limit the default limit is now 50K iterations regardless of recursion type.Ģ. With the introduction of FM 18 this has changed in two ways:ġ. SetRecursion ( expression maxIterations )īackground: since the release of FileMaker 7 in 2004, there have been two recursion limits: 10,000 iterations for standard recursion, and 50,000 iterations for tail recursion. Today we’re going to take a look at two new functions introduced in FileMaker 18: SetRecursion and While, and you can follow along in today’s demo files if you are so inclined.ĭemo files: While-Sandbox.zip and Maclaurin-Series.zip

In my opinion, both of them belong in your developer tool kit. Preliminary testing indicates that CustomList is faster under certain circumstances and While is faster under others. Author’s note: Inevitable comparisons will be drawn between the new While function and the venerable CustomList custom function, which I wrote about at length several years ago.
