DISPLAY Guest Storage (ESA/390)
be one to sixteen hexadecimal digits, separated with an optional underscore for
readability, leading zeros are optional. The default is zero.
Storage locations and the minimum amount displayed are rounded according to
the following conventions (in hexadecimal):
Option Start Minimum Length
T 10 10
M 10 10
K 7FF 7FF
S 1 1
I 2 2 - 6 depending on the instruction
N 4 4
U 1 1
% indicates 31-bit address indirection. Indirection means that the contents of the
specified address are used instead of the address itself. In this case, the 31 bits
at the specified address (the high-order bit is turned off) are used as the new
address for the Display command.
& indicates 64-bit address indirection. Indirection means that the contents of the
specified address are used instead of the address itself. In this case, the 64 bits
at the specified address are used as the new address for the Display command.
: END
– hexloc2
is the last of a range of hexadecimal storage locations whose contents are to
be displayed. If specified, hexloc2 must be equal to or greater than hexloc1 and
must be within the virtual machine storage size. The address, hexloc2, may be
from one to sixteen hexadecimal digits, separated with an optional underscore
for readability; leading zeros are optional. The colon (:) means the same as a
dash (-) when you specify a range of addresses.
Specify END if you want to display the remaining contents of storage. END is
the default if you specify a dash (-) or a colon (:).
END
. bytecount
is a hexadecimal integer designating the number of bytes of storage (starting
with the byte at hexloc1) to be displayed.
The byte count that you specify must have a value of at least 1 and may be
from one to eight hexadecimal digits long. Leading zeros are optional.
Specify END if you want to display the remaining contents of storage. END is
the default, if you specify a period (.).
BASEnn
displays the contents of guest storage using the specified starting address
(hexloc1) as a displacement from the address in the specified general register.
The specified register may be a decimal number from 0 to 15 or a hexadecimal
number from 0 to F. nn specifies an AR/GR pair if all the following are true:
v The L operand is specified
v The virtual machine is an ESA virtual machine
v The virtual CPU is in access register mode.
