Nowhere :-(


Several attempts have been made to "complete" the lousy Borland
grammar, with different results. I wrote (hacked ;-) an OPL parser,
some time ago, which at least could parse the D4 standard units. But
it looks impossible to extract a grammar from that parser, just as
it's impossible to extract a grammar from the Delphi compiler, even
with the source code at hand.


IMO even EBNF is inappropriate to express an unambiguous grammar for
OPL, and who ever has use for a context sensitive grammar?


DoDi


P.S.: Wofuer brauchst Du denn die Grammatik?
