At least I could find a grammar in BNF, by following the links in Wikipedia to <teampli.net/XPL/ldindex.html>. If I had to write an XPL compiler, as an excercise, I'd try to handcraft an LL(1) top-down parser for it. This approach will give more insight into "how to write a compiler", than understanding how to use a compiler generator. Finally that compiler can be rewritten in XPL. Much time will have to be spent in implementing the system library (Implicit Declarations) and memory management.
