Sample input:

FullList ( MyDatabase::Date ; 3 )
where Date's repetitions contain
""
5/15/2015
6/15/2015

Sample output:

¶5/15/2015¶6/15/2015

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

/* FullList ( Field ; NumberOfReps )
Field is full field name, eg MyDatabase::Date
NumberOfReps is the number of repetitions of that field that should be put into the list; it will always start with the first repetition and go to NumberOf Reps. FieldRepetitions can be used for this.

FullList is like List, except that it includes repetitions that are empty or zero. This is particularly useful when there are two associated fields, one fully populated (like dates of a month) and one partially populated (things that happened on those dates, where sometimes nothing happened), where you wish to find something in the second list and use its repetition number to determine the associated value in the first list.

Example FullList ( MyDatabase::Date ; 3 ) = 
¶5/15/2015¶6/15/2015
[when the field Date has three repetitions containing "" and these two dates]

I realize that this goes against convention which dictates that customs functions only interact with data, not fields. This was what was needed.

You could do the same thing by just reading the field; this allows for much faster computations by reading the field in one fell swoop, and thereafter keeping the information in memory.
