. bytecount
is a hexadecimal integer designating the number of bytes of storage (starting
with the byte at hexloc1) to be displayed. The sum of hexloc1 and bytecount
must be less than the bounds of addressable storage. This value is the lesser
of the storage size specified at system generation and the real storage size.
The specified byte count must have a value of at least one and may be from
one to sixteen hexadecimal digits, separated with an optional underscore for
readability; 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 (.).
1. While host storage is being displayed, the running of a virtual machine or
someone else using the STORE HOST command could cause data to be
changed. This could create an inconsistency in the data that is viewed.
2. In a multiprocessor environment, each processor has a prefix register that it
uses to relocate addresses between 0 and X'1FFF' to another page frame in
storage. The prefix register enables each processor to use a different page
frame to avoid conflict with other processors for such activity as interrupt code
recording. Thus, the range 0 through X'1FFF' refers to different areas of
storage, depending on which processor generates the address. All references to
first-level storage are handled as if they were made on the IPL processor.
3. If you use an underscore, it must be followed by eight hexadecimal digits.

Response 1:
Hhexloc word1 word2 word3 word4 [Key] [*TRANSLATION*]
is the response you receive with the T or N option. The translation is displayed only
if you have also entered the T option and is in either EBCDIC or (if the TX option is
specified) ASCII. The storage key is displayed on the first line, and at every page
boundary.
Response 2:
Hhexlochi_ Storage Key - [Key]
hexloclo word1 word2 word3 word4 [*TRANSLATION*]
is the response you receive with the M option. The translation is displayed in either
EBCDIC or (if the MX option is specified) ASCII. The storage key is displayed on
the first line, and at every page boundary.
Response 3:
Hhexloc *TRANSLATION* [key]
DISPLAY Host Storage
is the response you receive with the U option. The operand Hhexloc is the
hexadecimal location of the first data byte to be displayed. A minimum of 1
character and a maximum of 32 characters is displayed on each line. The contents
of storage are displayed in translated form and are in either EBCDIC or (if the UX
option is specified) ASCII. Periods in the display data represent nonprintable
characters. The storage key is displayed on the first line, and at every page
boundary.
