JOBPEK [CALLI 103]
In the calling sequence, the program supplies the following variables:
o
o
o
addr is the address of the argument list.
flags are one or more of the flags listed below.
count (JK.EWC) is the number of words to be read or written
(refer to GETTAB table .GTCNF, item %CNJPK), stored in Bits
8-17.
o JCH (JK.JCH) is the job/context handle of the job whose core
is to be read or written, stored in Bits 18-35.
o
a
readaddr is the 30-bit address giving the location of the
first word to be read.
writeaddr is the 30-bit address giving the location of the
first word to be written.
The flags and their meanings are:

JK.WRT
JK.UPM
JK.EVA
JK.AIO
Meaning
write the other job's core; if not set, read the
other job's core. When this bit is 0, the UUO
requires Spy privileges only.
Read the other job's UPMP (user page map page or
user page table). JK.WRT must not be set.
Source address is between .MCFV and .UUPMP; treat
it as if it were an executive virtual address
mapped through the specified job's UPMP. Both
JK.WRT and JK.UPM must be off.
Do not block if data is inaccessible (due to the
state of cache on SMP systems); set this bit only
if you set either JK.UPM or JK.EVA.
Notice that if the other job's core is to be read (JK.WRT is cleared),
then readaddr is a location in the other job and writeaddr is a
location in the current program. If the other job's core is to be
written (JK.WRT is set), then readaddr is a location in the current
program and writeaddr is a location in the other job.
SKIP RETURN
The specified words are transferred between the other job and the
current job.
