PL/I is a very good language; being general purpose, it has
everything you'd need.
Another langage is XPL, which was specially designed for
writing compilers. It has special features for string-handling
that make it fast for parsing text. (There's a text, "A compiler
Generator" by McKeeman et al, with the tools to implement
a language translator).
[I wouldn't use PL/I for writing a compiler. Its pointer handling and
strings are by modern standards pretty klunky. XPL is pretty cool for
a language designed over 50 years ago (really) but its main
improvement over PL/I, other than taking out most of the complication
not useful for system programming, was variable length strings in a
garbage collected heap. These days everything from java to python
to C++ does that for you. -John]
