I'm doing a presentation and wanted to quickly mention how the mainframe
architecture instruction set has grown. Does anyone happen to know the
number of different unprivileged machine instructions there were in the
early 370 days versus the latest soon-to-be-released z/Architecture
instruction
Assuming that PLIST points to a valid remote parameter list, I think that
your best bet is to dump PLIST before the call to make sure it looks okay
and to turn on Trace Resolver output with a
//SYSTCPT DD SYSOUT=*
I'm not sure how you're getting your base resolver files. Have a look at

Hi, Kirk --
Don't you need to bias R4 by adding +2048 (CEEDSAHP_BIAS) to it? In other
words, isn't R4 really pointing to DSA - CEEDSAHP_BIAS?

Hi, Dave -
As I read the docs, NOTE only works after a READ or WRITE. You'll get an
invalid value if you use it after a FIND or POINT.

Hi, Paul --
In a BAKR R14,R15 instruction, the R14 value is the value to which the
branched-to routine will return when it executes the PR. So your statement
"Register 14 (operand 1) would contain the next sequential instruction" is
correct if you're talking about the value of R14 _before_ the

Hi, Abe -
In the version of the PoP that I'm looking at, it states that ". Except where
otherwise indicated, ...DFP [is defined] in terms of the right-units view. So I
think that's just a convention in the documentation.
As far as LUV vs RUV, a given value is represented the same in a

But you need to look at the bias for the exponent. Both views would be encoded
the same. I guess I didn't explain this very well before but this example will
help. For the short format, there are 7 significant digits. For the LUV, bias
of the exponent is 95. For the RUV, bias of the
- Biased Exp = 98
007E-4 - Biased Exp = 97
070E-5 - Biased Exp = 96
700E-6 - Biased Exp = 95
Which clearly shows that in the encoded format the RUV vs LUV is not relevant.
Thanks a lot for helping me understand.
Kind regards,
Abe
