PosInSortedList (String,Array) : Number

Scans a string array looking for a match on string in a sorted array and returns the array index of the first matched string if found or a zero if not found. The array must be in sorted order. A binary search is used to make this command very fast.


Example:

   var List
   List[1] = 'Adam'
   List[2] = 'Ben'
   List[3] = 'Don'
   List[4] = 'James'
   List[5] = 'Kate'
   SortArray(List)                        ; List is sorted
   Writeln PosInSortedList('James',List)  ;returns 4
