DUMP Registers
Dump Register
ECR nn = ctlreg0 ctlreg1 ctlreg2 ctlreg3
is the response that is sent to the virtual printer when you dump the control
registers using D X or D XG from an ESA/390 or ESA/XC guest. nn indicates the
first (or only) register whose contents are dumped.
The content of each register is dumped in hexadecimal. Up to four registers per line
are dumped for each range you specify. If required, multiple lines are dumped to a
maximum of four lines.
Response 7:
HCPCDE6150E An option has been specified that is not valid in
ESA/390 mode.
is the response you receive when you dump the control registers using D XH from
an ESA/390 guest (an appropriate message will be issued from an ESA/XC guest).
Response 8:
Dump Register
ECR nn = ctlreg0l ctlreg1l ctlreg2l ctlreg3l
is the response that is sent to the virtual printer when you dump the control
registers using D X from an z/Architecture guest. nn indicates the first (or only)
register whose contents are dumped.
The content of each register is dumped in hexadecimal and represents the low half
of the full 64-bit register. Up to four registers per line are dumped for each range
you specify. If required, multiple lines are dumped to a maximum of four lines.
Response 9:
Dump Register
CRG nn = ctlreg0hctlreg0l ctlreg1hctlreg1l
is the response that is sent to the virtual printer when you dump the control
registers using D XG from a z/Architecture guest. nn indicates the first (or only)
register whose contents are dumped.
The content of each register is dumped in hexadecimal and represents the the full
64-bit register. Up to two registers per line are dumped for each range you specify.
If required, multiple lines are dumped to a maximum of eight lines.
The high and low halves of each register may be separated by an optional
underscore for readability. To have the underscore displayed, use the SET
UNDERSCORE command.
