Software tips, techniques, and news.
Sometimes smallest features offer the biggest impact. The new While function, which gives the ability to loop within a calculation, drastically reduces the need for one-off recursive custom functions, speeding up development in any part of FileMaker that requires looping in a calculation. Let's take at how it works.
The format of a while function is broken into four parts: initial variables, the condition, logic, and the results. The function repeats the logic section until the condition is false; that is how the function provides the ability to loop. In the example below the While function returns a list of numbers 1 through 5:
While ( [ count = 1; numberList = "" ]; count < 6 ; [ numberList = numberList & (count) & "¶"; count = count + 1 ]; numberList )
The function returns:
1 2 3 4 5
With the advent of the While function, development of FileMaker applications will become a simpler and quicker process, eliminating the need for one-off recursive functions. Download the demo file to try out the new function!
