Raphael:

I did another search and again there is no Foxrun.pif file anywhere on my hard drives.

I discovered that MODIFY FILE FOXRUN.PIF causes the program to open a file called FOXRUN (no suffix) and this is why I ended up with machine language.

Anyway, I have found a solution using Comspec and this works fine, so I am OK.

Thank you for your reply.
