If I recall correctly, EPD was a standard invented by John Stanback and promoted by Steven J Edwards. Stanback used it to communicate moves back and forth between programs via a text file. Edwards apparently had an aggressive plan to extend this via a suite of weirdly named utilities that I had never heard of before, so I expect they never were written. These days, EPD is used to store test suites. Some of the EPD operands appear to suggest the idea that you will run the EPD through your program, and out the other end will pop another EPD, which has a bunch of fields filled in that can be used to calculate and interpret results. Does anyone use these fields? Does anyone in practical reality ever use the fields other than "am" (avoid move), "bm" (best move), "id" (a title), and maybe "hmvc" and "fmvn", which are the two fields of the FEN that don't appear in the EPD? My guess is that all of the opcodes are dead except for these five. Anyone else have a contradictory opinion? bruce
