Subject: Re: File.open error when variable is used

The code is running on:

      Aix 6100-06
      Ruby 1.6.6 (2001-12-26) [powerpc-aix4.3.3.0]

This is the parameter line in a ksh script calling the ruby program 
called execluderow2.rb

   excluderow2.rb INFILE=invrolla.txt,OUTFILE=invrollb.txt

This is the method which is called to parse the input parms.  Without 
the 'Crazy' fig shown below, the program stops.  The error only happens 
when executing from aix cron and therefore the error code (if one is 
given)cannot be seen.  If I add the crazy fig shown below, all the file 
opens later in the code work with no issue or error.

def parseArgs args
   args = args.split(",")
   args.each {
      |arg|
      puts arg
      keyword, value = arg.split("=")
      case keyword
         when "INFILE"
            $inFile = value
         when "OUTFILE"
            $outFile = value
      end
    }

   # Crazy fix
   if $inFile  == "invrolla.txt" then  $inFile  = "invrolla.txt"  end
   if $outFile == "invrollb.txt" then  $outFile = "invrollb.txt"  end
end

This is one of the file opens later in the code.  It won't work without 
the crazy fix.

   outputFile = File.new($outFile, "w")
