' Return the largest value in a single-precision array

' In Visual Basic:
'
' Declare Function MinS! Lib "MINS.DLL" (x!, ByVal TotalElements&)
'
' Sub y()
'   ReDim x!(1 to 100)
'   '** Fill the array here **
'   Value! = MinS!(x!(1), 100)  'pass the first element and total elements
' End Sub
'
'

  DIM x AS SINGLE PTR
  DIM z AS SINGLE
  DIM i AS LONG

' ** Assign address of first element to pointer variable
  x = xPtr

' ** Loop through all the elements
  FOR i = 0 TO nElems - 1

' ** If element is larger than current largest, use it instead
    IF @x[i] > z THEN
      z = @x[i]
    END IF

  NEXT i

' ** Return the largest value
  FUNCTION = z
