function parm_val(fullS,parmS)
//
// Name:	parm_val (source_output)
//
// Date:	7. Marts 1997
//
// Purpose:	This function gets specific data in the searchstring of the URL
//
// Variables:	The first input should be the string to be manipulated (which could
// 		be location.search). The second input should be the part of the
//		string that we're searching for. E.g. we want to know what the user
// 		typed as paramters in this string "?user_typed=ABC". To get ABC as
//		result from the function call it with theese parameters:
//		parm_val(location.search, "user_typed")
//
// Author(s):	Joachim Fuglsang-Frederiksen (JFF), Werner Knudsen (WEK)

// History:
// 07-03-97  JFF  Created
// 19-03-97  JFF  Changed for-loops to while, function working as of now
// 19-03-97  JFF  Comments added
// May 1997  WEK  Various changes
// Jun 1997  WEK  Now works with Netscape 2.02
//           WEK  Now handles empty parameters: ?x=&y=5 denotes x empty
