Does anyone have the grammar to PL/I? Yacc+lex prefered but i'll take
anything. Thank you.

[Good luck, PL/I has no reserved words so it's hard to handle with yacc and
lex, e.g. IF IF = THEN THEN IF = ELSE; -John]

If you are going to do anything with PL/I, the definitive source is the
TSI compiler from Translation Systems Incorporated. With the exception
of the IBM offering, all of the PL/I (Subset G) compilers that I have
encountered have been based on the TSI implementation. As has already been
noted here, PL/I does not have any reserved words making yacc/lexx a
formidable task. The TSI technology is well tuned to PL/I and most
importantly has all the aspects of the language layed out.
I have no association with TSI but have worked on a PL/I compiler from
the TSI code in the past.
