Category:  Special function

\\ 
=====Description=====
This function returns the position index of //value// in a list of values (//text_list//), separated by //delimiter//. 

\\ 
=====Use cases=====
This function makes it possible to define EasyMorph expressions externally using parameters.

\\ 
=====Arguments=====
^Argument^Type^Description^
|value|Any|The value to search for within //text_list//.  This argument is implicitly converted to text.|
|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.|

**Return value type:** Number

\\ 
=====Remarks=====
This function returns 0 if //value// is not found within //text_list//.

The values in the delimited string (//text_list//) are always considered text, even if they look like a number.  The first argument (//value//) is implicitly converted to text.

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

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

  match(5, '5;55;555', ';')  //Returns 1

  match('55', '555;55;5', ';')  //Returns 2

  match('11', '4;8;12;16;20', ";")  //Returns 0  ('11' is not present in the list.)
