Hi there

my version of ksh:

$what /bin/ksh

/bin/ksh
         Copyright (c) 1989, 1993
        $OpenBSD: mknod.c,v 1.1 2005/10/06 06:39:36 otto Exp $
        PD KSH v5.2.14 99/07/13.2

I cannot figure out what is wrong with the following code

#! /bin/ksh
for (( i=9; i>0; i-- ))
 do echo "$i"
 done

output:
syntax error: '((' unexpected.
why?
regards
