Yup. Sometimes, in particular during testing and in embedded system applications it is very convenient that you can safely EXIT the primary shell. I have reported this bug in 4DOS (still in the current build) to JP Software more than once, but unfortunately they didn't seem to understand that being able to EXIT the primary shell is a DOS 6.0+ /feature/, that should be supported by 4DOS as well - it would be trivial to special case this in their product. The background: In order to avoid the problem in older versions of DOS (which did *not* prompt you to enter a new shell name when you were exiting the primary shell), they implemented some detection code into 4DOS, so that it will usually (that is, in most common cases) auto-detect if it is loaded as the primary shell and then insert /P by itself. Admitted, this was a safety feature before MS-DOS 6.0, PC DOS 6.1 and Novell DOS 7 times. However, today it is a small, but unnecessary restriction. Maybe, if more people would report this very problem to JP Software, they would see some reason to improve their current way of doing things? ... > This way you can run one program as a shell, exit it, > run another one, and so on.

DR-DOS 7.02+ has a very similar extra added. If you happen to fall back to the 'mini-prompt' in the DOS BIOS, it will give you a chance to enter a new path to a shell, but if you just press ENTER it will retry to reload the previous one, including the old command line arguments.
