Au contraire!  DOS 3.1 did have the /E switch available.  PC-DOS and many
MS-DOS versions didn't document it, though.  The systax is not the same as
that in 3.2+.  The /E:nnn refers to the number of _paragraphs_ to alloc-
ate to the environment; thus, /E:32 will set up a 512 byte environment.
I suspect Microsoft anticipated the change and simply dropped the documen-
tation from 3.1.  It works in Compaq, IBM, and at least one 'generic' ver-
sion I've used.
