Thanks, that will certainly help! Although I have not tested it yet I can clearly see the advantages of your changes. I already know that 'parse itself shaves quite a bit of time compared to 'while. And there are other goodies: precompiled fetch, to char! instead of to-char, and inlining. I was using to-binary (your to binary!) before, but I dropped it since it seemed to me slower than the explicit construction of integers. But I probably missed the case of 4-byte integers where to binary! might be in fact faster than the by-hand construction. I'll report back, after the final revision of the decoder and the verification whether or not the latest simplified algorithms properly work for all cases. The final step will handle the little endian vs. big endian issues. All the best, Jan
