Bad use of ElseIf

ElseIf

; sample arrays; real ones are bigger
$FUNCS = StringSplit("funcA|funcB|funcC|funcD|funcE" , "|")
$SPECS = StringSplit("descA|descB|descC|descD|descE" , "|")

MsgBox(4096,"", lookup("funcD") )
Exit

Func lookup($keyword); binary search that returns element
  Local $lo = 1, $i, $hi = UBound($FUNCS)-1
  Local $lo = 1, $i, $hi = $FUNCS[0]-1
     
  While ($lo <= $hi)
     $i = Round( ($lo+$hi)/2 )
     If $keyword > $FUNCS[$i] Then
        $lo = $i + 1
     ElseIf $keyword < $FUNCS[$i] Then; not sure what you wanted to do
        $hi = $i - 1
     Else
        Return $SPECS[$i]
     EndIf
  WEnd
  Return ""
EndFunc
