Many years ago at Hagerstown MD, they had a computer (I think it was an NCR3 or 3000, it's just been too long ago) that at odd points would just fail. My father was an RF tech working on radios, and had a contract for the Police Department... so I will make this short. It turns out that a few

You can add KEYLEN with the length of the key (default 0) https://www.ibm.com/docs/en/zos/2.1.0?topic=kp-syntax-4 and KEYOFF with the offset of the Key (default 0). Copies the high key value from the block into the key field of CKD then you can add skip sequential processing to Cobol, PL/I, ASM,

Just before I worked with mainframes I drew maps on a computer that had a big display, a small drawing pad and pen, and a large light table with a "puck" for tracing existing maps into the computer. Both the puck and pen worked by receiving a magnetic signal from the pad or table in order to

Well, I guess RESMGR is documented as only supporting 24/31 bit

It does not check SYSSTATE AMODE64. But even so, as it ends up issuing a PC there is no real reason not to support 64 bit. Using LLGT to get the CVT address is common in other macros. Document that parameters need to be below the bar. In other cases I have used OPSYN to examine instructions and

Re: PC Interference from shredder Was: Kinda fun

I think shielding of the PC itself is unlikely the problem, unless the case is not properly closed.  All PCs I have ever seen have metal cases, which if properly seated and grounded act as a RF shield, inbound and outbound. Any electric motor could be producing power transients at power

Re: Is True Skip-Sequential Processing Possible with RECFM=FB,DSORG=PS?

If the question is whether there is direct z/OS support for this for FB PS datasets, the answer is probably no, although if you get down to assembler coding, there are ways to get close. It looks like you could potentially design and implement an I/O interface routine (in assembler) using
