Well, I want to calculate an interval between two STCKE time values.
It seems like this is a great opportunity to use SLBGR, but I
don't have a lot of confidence in the right way to do this.
Suppose me ending timestamp is in datetimen and my starting
timestamp is in datetimes, defined this way:
datetimen ds cl16
datetimes ds cl16
Here's what I'm thinking:
LMG R2,R4,datetimen - put datetime into R2/R3
(use 64 bits in each reg)
and put datetimes into R4/R5
(use 64 bits in each reg)
SLBGR R3,R5
SLBGR R2,R4
after this, I think the difference is in R2/R3 as a
128-bit integer
Is this right?
If so, then I can store R2/R3 into a 16-byte area and use
CONVTOD to calculate the difference. Somehow that seems a
little off.
Would appreciate any insights / suggestions for this.
Thanks.
