FUNCTION:
nbrList ( items ; counter ; result )

CALL:
nbrList( "firstName¶lastName¶zip" ; "" ; "" )


I'm looking for a way (if possible) to improve it so that instead I can call it without the placeholders, like this:


nbrList( "firstName¶lastName¶zip")


and get the same result:

1. firstName
2. lastName
3. zip


All suggestions welcome. Thanks in advance.



/*

// nbrList ( items ; counter ; result )
// Recursively loops thru the elements in a return-delimited list and adds the order number to each element.

Sample Input:
nbrList( "firstName¶lastName¶zip" ; "" ; "" )

NOTE: Do NOT enter any values for the "counter" and "result" parameters - only enter empty string (""); those parameters exist solely as placeholders for the tail recursion.

Sample Output:
1. firstName
2. lastName
3. zip

Description:
This function will recursively loop thru the elements in a return-delimited list adding the order number to each element.
