Universal custom function - write your function outside the CF editor

Sample Input:
Let([
datalist = "2¶7¶3";
multiplyValues = "GetValue($param; 1) * Case( ValueCount($param) > 1;
FormulaCall ($formula; RightValues($param; ValueCount($param) - 1));1)"];
FormulaCall( multiplyValues; dataList)
)
Sample Output:
42


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

Description:

Universal recursive custom function
Write your functions OUTSIDE of the custom function editor and just pass them to this function.
Only two parameters can be passed;
your function; and a parameter list
Use $variable or $$variables within your
function expression if necessary

==========
Example
==========

let( [
$formula="";
$separator = " "; //tab
$cellSeparator ="</td>¶<td>";
rowStart = "<tr>¶<td>";
rowEnd = "</td>¶<tr>";
dataList = "2¶3¶4¶77¶37¶98" ;

multiplyValues = "GetValue($param; 1) * Case( ValueCount($param) > 1;
FormulaCall ($formula; RightValues($param; ValueCount($param) - 1));1)";

addValues = "GetValue($param; 1) + Case( ValueCount($param) > 1;
FormulaCall ($formula; RightValues($param; ValueCount($param) - 1)))";

factorial = "GetValue($param; 1) * Case( $param > 2;
FormulaCall ($formula; $param - 1); 1)";

ListValues = "GetValue($param; 1) & $separator & Case( ValueCount($param) > 1;
FormulaCall($formula; RightValues($param; ValueCount($param) - 1)))";

htmlRow ="Let( N = valueCount($param);
Case( N > 0; GetValue($param; 1) & case( N>1; $cellseparator) &
FormulaCall ($formula; RightValues($param; ValueCount($param) - 1)
);
))"

] ;
FormulaCall ( multiplyValues ;dataList ) & ¶ &
FormulaCall ( addValues ; dataList) & ¶ &
FormulaCall ( ListValues ;dataList) & ¶ &
FormulaCall ( Factorial; 6) & ¶ &
