  Sample input:
mkConcatColumns(
mkConcatColumns(
list(field1),
list(field2),
" -- "),
list(field3),
" / ")

(For a table with four records and three fields:

field1, field2, field3
-- -- --
a, b, c
1, 2, 3
red, blue, green
east, west, north)
  Sample output:
"a -- b / c¶
1 -- 2 / 3¶
red -- blue / green¶
east -- west / north"

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

This will take two ¶-delimited lists and concatenate with a user-defined delimiter so the output is:

list1Value1[user-specifieddelimiter]list2Value1¶
list1Value2[user-specifieddelimiter]list2Value2¶
list1Value3[user-specifieddelimiter]list2Value3¶
...
etc.

You can nest this function to add further columns.

Functionally, this means you can use it like the list() function, but include multiple fields from each record on each row of the result.

For instance,

mkConcatColumns(
mkConcatColumns(
list(field1),
list(field2),
" -- "),
list(field3),
" / ")

will give the result

"[Record 1 field 1] -- [record 1 field 2] / [record 1 field 3]¶
[Record 2 field 1] -- [record 2 field 2] / [record 2 field 3]¶
[Record 3 field 1] -- [record 3 field 2] / [record 3 field 3]¶
...

and so forth.
