I'm not sure we're ever going to see college courses offered for Pick, however I learned about hashing and linked frames in a college course. It wasn't a class in "Pick" just in Data Structures.
We just have to learn how to market pick as a hashed database using continuously resizeable linked structures. Essentially at the upper level the Pick database is just a set of blocks with pointers, that's your real "file", the contents are not material to that level of abstraction. Hashing is then a way of overlaying that layer with a deeper layer of meaning. We completely avoid the need for a jump table to the contents, as all the frames are direct access, then you walk the frame in that lower layer of abstraction. _______________________________________________ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
