Maybe I shouldn't have said "used LALR parse tables". I should have
said "generated LALR parse tables". The XPL grammar analyzer
generates something the author called MSP tables. I was thinking it
would be more useful if it generated LALR tables. Since I am in the
process of writing an XPL compiler I thought I could modernize the
grammar analyzer with something that would make the package more
useful.


I have no interest in converting tables from some other tool.


I was unaware of goldparser.org. Thanks for the reference. Currently
the goldparser project is not releasing the source of the grammar
analyzer so it does not help me find a solution.
