\\

\\ 
=====Arguments=====
^Argument^Type^Description^
|index|Number|The position of the value to return from //text_list//.|
|text_list|Text|A text-based delimited list of values to search for //value//.|
|delimiter|Text|The character(s) used to separate the individual values in //text_list//.  This can be more than one character.|

=====Remarks=====
Regardless of what the return value appears to be (number, Boolean, text), this function //always// returns a text value.

The values in the delimited string (//text_list//) are always considered text, even if they look like a number.

This function returns an empty value if //index// exceeds the number of delimited values in //text_list//.

//Delimiter// may contain more than one character.

\\ 
=====Examples=====

  pick(3, 'Please don’t stop the music', ' ')  //Returns 'stop'

  pick(2, '2,4,6,8,10,12', ',')  //Returns '4'  (This is a text value, not a number.)

  pick(5, 'Sally;Bob;Mary;Sue', ';')  //Returns an empty value  (Only 4 values within the text list.)
