	returns empty if the search string is not found. Does not use local variables anymore.
v.2.1 Sept 2007
v.2, Mar 2007
v.1, Jan 2007

v2 adds inclusion boolean parameter.
v2.1 corrects a bug with searchstring

extracts the end of a text, based on a search string and an occurrence number
occurrence can be positive (starting from the beginning of the text) or negative (starting from the end)

e.g. text.after ( "1234512345" ; "2" ; -1 ; 0 ) = "345"

see also text.before, text.between, and text.betweenNext functions

Let ([
	_occurrence = Case ( not _occurrence ; 1 ; GetAsNumber ( _occurrence ));
	_pos = Case (
			_occurrence > 0 ;
			Position ( _text ; _searchString ; 0 ; _occurrence ) ;
			Position ( _text ; _searchString ; Length ( _text ) ; _occurrence )
		) ;
	_pos = Case ( _pos ; Case ( _include.b ; _pos ; _pos + Length ( _searchString ))) ; 
	_result = Case ( _pos ; Middle ( _text ; _pos ; Length ( _text )))

Examples need to add the include_1 parameter, which I learned to use a zero for after looking at the After custom function

Hi Fabrice, I use your function. But what happens if the searchstring does not exist in the text?

		Fabrice Nordmann, 1-more-thing Sep 2, 2017
Hi Jaap, you're correct. I updated it here so it returns empty. Fabrice
