  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

Takes a sorted ascending list of numbers delimited by the ¶ character (SList) and searches for the number Value in the list. Returns the first line number that matches Value. If Value is not found in SList then the function instead returns the line number of the next highest value in the list.

The value of Offset is added to the returned value.

If the search value is empty, returns 0 (plus Offset)
If the sorted list is empty, the search value is treated as the next highest value and returns 1 (plus Offset).

Assumes the SList is well formed without preceding or trailing return characters.

If SList = "2¶4¶20" and Offset = 0:
then if the Value is empty or equals 0 or 1 or 2, the function returns 1.
If the Value is 3 or 4 the function returns 2
If the Value is between 5 and 20 (inclusive) the function returns 3.
If the Value is larger than 20 then the function returns 4.
