DISPLAY Host Storage
at the address specified as an EBCDIC string or as an ASCII string if the X
option is specified. The specified address range is not boundary-aligned.
The storage key is displayed on the first line, as well as at every page
boundary.
M displays the contents of storage in hexadecimal and character form. A header is
displayed as the first line, and at every page boundary and contains the
high-order 32 bits of the 64-bit address along with the storage key. Storage is
displayed in word segments. An address range is displayed starting at the X'10'
byte boundary in which the specified address resides. X'10' bytes of storage are
displayed per line. The hexadecimal display is followed by the storage as an
EBCDIC string, or as an ASCII string if the X option is specified.
If you do not specify any of the options T, M, K, S, I, N, or U, the contents of
storage are displayed in hexadecimal word segments.
0
hexloc1
is the starting storage location that is to be displayed. The address hexloc1 may
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 bounds of addressable storage. The address hexloc2
may be from one to sixteen hexadecimal digits, separated with an optional
underscore for readability; leading zeros are optional. A colon (:) means the
same as a dash (-) when specifying 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 (:).
