Microsoft C 5.1 or better.  The Borland C compiler refused to compile
eval.c and the grammar file last time I tried (two years ago, could
have been fixed by now.) GCC for 386 MS-DOS (as currently posted in
c.b.i) would be an interesting experiment, which I will attempt when I
find time.  Expect problems with its C libraries.

They should.

>How much memory does the perl program take on DOS?
As much as you have and sometimes a bit more than that.  The executable
is around 300K.  You can write moderately complicated programs (up to
say 700 lines) without a memory problem if you do not use a lot of data
space.  Furthermore many MS-DOS perl versions swap themselves out of
memory when doing pipes or system() and thus occupy only around 4K at
that time.  The only time when I have found the DOS memory to be a
problem was, when I was using a big associative array to hold data.
