I found the reason why convert/misc/md5 didn't work on the 64-bit architecture. The failures came from the rot function -- it was ok for 32-bit ints, but wrong for 64-bit. This is what works ok:
rot=: 16bffffffff and sh or ] sh~ 32 -~ [ NB. (y << x) | (y >> (32 - x)) I saved it in https://github.com/georgiy-pruss/2-J/blob/master/md5.ijs Probably it can return to the convert family. It can be useful when the jqt library is not available. Also T can be calculated during the initialization. It turned our they are just sine values! ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
