Is this all the DOS Watcom application does? Just ask for some basic info to pass back to the caller (to run as parameters to the ghosting app)? > We had a clumsy turbodisk memory partition (there is no writable storage on > our system when running under FreeDOS), so we write a batch file in that > partition with the environment variables we need, and then the calling > script executes than batch file on exit to "pickup" those set environment > variables. > > Sounds clumsy?

I almost suspect that you're accidentally using 4DOS and tripping over something minor. I think Bernd starting (optionally?) using that, and it's not always obvious. I don't think FreeCOM's binary has literally changed at all (except for some SVN source tweaks). > Is there any easier way to achieve what we need?

Let's face it, DOS .BAT is almost useless. However, it's unlikely you'll migrate to REXX just for this, so I'm not that naive, but indeed, IMHO it probably could help you.
