CBT Tape loaded into an INFOMVS database

2014-06-01 Thread Sam Golob
Hi Folks, I'd like to take a straw poll. There is some JCL in the CBT Tape to load an INFOMVS database with CBT Tape data. Should I get rid of it? Does anybody use INFOMVS anymore? Here's a chance to say what you think. Maybe I'll just separate it out and move it to the pds which is F

Thanks, John, exactly the sort of information I was looking for. Do you recall what the hardware was? I am leaning toward aligning it. If I can gain a couple of milliseconds of CPU time per customer per day in return for coding + 1 & 0xfffe once I think that's worth it. OTOH, it will make the

There is a performance penalty. I have measured it for aligned and unaligned signed halfword, i.e., signed binary fixed(15,0), in compiled PL/I code and found that it is usually about 13%, which may be trivial or important depending upon context. More important in multiple-CP environments, I thi

Shane Ginnane's point is well taken. Erwin Schrödinger (1887-1961) described entanglement as one of the 'central principles' of quantum mechanics; and there is a discussion, pellucid but not for mathematical dropouts, of entanglement in the first English-language edition of John von Neumann's book
