In the CP/M-80 community there is a compiler-making tool called META4
that is in either the SIG/M or CPMUG libraries that allows you to
create your own lanugage compilers.  An example is given to make a
mini Algol-flavored language, although you don't code them up with BNF.
It was written up in DDJ some years back as a reprint from an ACM journal.
It is a descendent of META2, which was originally born on early-60's
mainframes back in the memory-lean days of 64K 360's.
