Hello there,

I need to build parsers for Natural (for Adabas), PL/1 and Cobol

To do it, the formal language specifications required. Fortunately, it
was not a problem to find them for Cobol.

But after several days of uncuccessful searching I have no idea about
how to find the same data for Natural and PL/1.

Can anybody help me? Where could I find these specifications (in yacc,
bison, BNF or any other format)?

Thanks in advance,
Igor Sindyakov
[There's an ANSI PL/I standard with syntax diagrams. Since PL/I has no
reserved words, it's hard to parse with the usual automated tools. Nobody's
ever asked about Natural before. -John]
