Re: ksh scripting problem

Okay.  Here's a real puzzle and I don't think it has anything to do with 
\r.

This doesn't work.  It hangs at the if statement, which doesn't execute.
        p=$(echo $line | tr -d '\r')
        ((++wkcnt))
        if      ((p>0))
 
This does work
        p=$(echo $line | tr -d '\r')
        ((++wkcnt))
        #
        if      ((p>0))

As does this
        ((++wkcnt))
        p=$(echo $line | tr -d '\r')
        if      ((p>0))
 
You need something after ((++wkcnt)) for if to work and that makes no 
sense to me at all.
