Well, the list is a fuzzy memory, but thanks to a great guy who read in my magtapes, I was able to go back and UTSL.

Here is the list, minus the various copies and stubs.  The definitions were written in a notation I made up called Language Description Language (LDL)

• ada.ldl (DOD language for embedded systems)
• asple.ldl (A Simple Programming Language Example, ACM Computing Surveys 6/76.  This was useful for getting the semantic checking working.)
• c.ldl   (no typedef or cpp)
• expr.ldl (a simple expression language)
• ldl.ldl (the Language Description Language itself)
• lisp.ldl
• pascal.ldl
• rigel.ldl (a database language from UCB)
• text.ldl (plain text)
  

One of these days in My Copious Free Time, I hope to get this beast "BABEL" running again.  It was painfully slow on a Vax, but it might be OK on today's hardware.

When I was at Berkeley working on my dissertation, I wrote a tool that would
let you edit a text file written in any language you could define with a
grammar, with syntax and semantic error checking while you edited.  I had
grammars for several popular (in 1980) languages.

My curiosity is piqued.  What were these languages?
