DUMP
3. You can assign a dumpid to any dump that you create by means of the DUMP
command. Note, however, that even though you can use a single DUMP
command to make multiple DUMP requests, you can assign only one dumpid
per command.
The dump identifier is an asterisk (*) followed by a 1- to 97-character string
(truncated to 80 characters for a z/Architecture mode guest) that is to be
assigned to the dump. If specified, the dump identifier must be the last operand
you enter on the command line. Blanks are permitted in the dumpid.
For example, dump G *general registers creates a dump of your general
registers and assigns the dump the identifier “general registers”.
4. As each request is processed, a message is sent to your display device. This
permits you to stop DUMP processing by pressing the PA1 key. When the
command terminates, you may enter another command.
5. The defaults for the following DUMP operands are:
Operand
Default Before Rounding
G 0-end
G- 0-end
G-5 0-G5
G5- G5-end
G5 G5
T error
T- T0-end
T-1000
T0-1000
T1000-
T1000-end
T1000 T1000

PSW current
6. When dumping a range of addresses or subchannels, the command operand
must be followed by an address, a range, or a colon (:), hyphen (-), or period
(.) which forms a range. When dumping registers, the command operand can
stand alone.
7. If you enter a command line that contains an operand that is not valid, the
DUMP command terminates when it encounters that operand. Any previous
valid operands are processed before termination occurs.
8. The DUMP command lets you dump information in the following formats:
v Hexadecimal string / word segments
v EBCDIC translation for uppercase letters and numbers 0 through 9
v Hexadecimal word segments with EBCDIC and ASCII translation
v Instruction
v Storage key
Note: The EBCDIC translation is displayed only when the storage location
contains the hexadecimal representation contained in a system
translation table. This table is tailorable by the system programmer via
the system configuration file. The IBM-supplied table supports translation
for the hexadecimal representation of the digits 0 through 9, the
