About forty years ago, FORTRAN was called "the universal assembly language." People who invented new languages generated Fortran code because it's easier than generating machine code, and your new language would instantly run on every machine that had a Fortran compiler. Now that's mostly done in C. I wrote compilers for several "small" languages in Fortran. I use a Pager's method LR parser generator written in Fortran. My 1401 Autocoder cross assembler is in Fortran.
