Hello All

I'm looking for a grammar and language definition for the JOVIAL
language. I found the start of one from a fellow a Hughes several
years ago, but it's very incomplete. I have the language
specification (J73) but it's poorly laid out with respect to setting
up for what I know to be a left recursive language. I tried finding
an Algol 58 compiler definition too, but I came up empty there too.
There's several interpreters, but no yacc/lex files there at all.

Question: If you have a language and grammar for JOVIAL, will you
share it with me? I want to make a tool that converts from JOVIAL to
C/C++ or to ADA. I don't care if it's exactly 1 to 1, because the
entire output will need to be examined anyway for verification. All I
want to do is the gross conversion right now.

Any info, please send to
