A very valuable exercise! However,
_ (whether infinity or the negation sign) is not a <digit> There are two 0 digits. <number> is not defined (as used in numeric | number . | number . number ) I presume that the various flavors of numbers (complex, rational, exponential, etc) will be subjected to the BNF treatment Rules such as "words which begin with : or with . MUST be preceeded by whitespace. " and others should find expression in the BNF Raul Miller wrote: > I have put up a draft copy of a BNF representation of J's syntax on the jwki. > > http://www.jsoftware.com/jwiki/Backus–Naur%20Form > > If anyone has time, could you look it over, for silly obvious type errors? > > Thanks, > > ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
