The following are examples of DCP entries that produce full storage
displays.
dcp 1 dcp 1-dcp 0- dcp t:end
dcp t dcp 1: dcp 0: dcp t:end
dcp -dcp t: dcp 1-end dcp O:end dcp dcp 1. dcp t-end dcp 1.end
dcp • dcp t. dcp O-end dcp O.end The following displays all of storage three times because of the
embedded blanks:
dcp 1 • t
For default values (that is, the beginning and ending of storage)
to be applicable, one operand must be specified.
3. In attached processor applications, the PSA values for the main and
the attached processor are not located at absolute page zero but
are displacements from it. Therefore, prefixing the hexadecimal location with an ft or N will add the hexadecimal value to the
displacement of the location of the assigned PSA for the designated
processor; for example, dcp .40.8 Displays the CSW of the main processor.
dcp n78-7f Displays the I/O new PSi of the attached processor. Requested locations are displayed in the following format: xxxxxx = wordl word2 word3 word4 [key] *EBCDIC trans1ation* xxxxxx is the real storage location of wordl. word1 is displayed (word-aligned) for a single hexadecimal specification. Up to four words are displayed on a line. If required, multiple lines are displayed.
EBCDIC translation
is displayed aligned to the next lower l6-byte boundary if Thex10c is specified. Note that non printable characters are
displayed as a period (.). If the location is at a 2K page
boundary, the key for that page is also displayed. The output
can be stopped and the command by pressing the ATTN key (or its equivalent).
Section 3. CP Commands 61

DEFINE B Use the DEFINE co •• and to redefine the status of a 3330V volume. For exaaple, a 3330V .ay have been defined as VIRTUAL allowing it to be
dedicated to a specific virtual .achine. However, if that virtual
.achine is not logged on, you can redefine the 3330V as SYSVIRT to make it available to the control prograa for .ounting system voluaes. The
for.at of the DEPINE co.mand is: DEPine { SYSVirt} Virtual raddr1 [-raddr2] _____________________________________________________________ ---J SYSVIRT specifies the desired status of the 3330V. This
reserved for CP. V8/370 system volumes that are voluaes can be aounted on SYSVIRT 3330V devices.
status is ftSS 3330V VIRTUAL specifies the desired status of the 3330V. 3330V devices that
are dedicated or attached aust use the VIRTUAL feature.
raddr1 [-raddr2]
specifies the device address or range of addresses to be
defined. If a range is specified, all 3330V devices in the
range are set to the desired status. !!sage Notes:
If an 8SS voluae is aounted and not currently in use on a 3330V that is
redef1ned, the control program cuases the voluae to be demounted before
the DEFINE co •• and coapletes. An 8SS volume deaount should be forced to
redefine the status of the 3330V on which the volume is aounted.
Responses are sent to the operator who issued the DEFINE coamand. The
responses show the device status following execution of the command. Possible responses are:
raddr NOT KNOWN The raddr is not a valid device address. No action is taken for
the raddr.
raddr NOT 3330V The raddr is not a 3330V. No action is taken for the raddr.
raddr ALREADY SYSVIRT raddr ALREADY VIRTUAL The raddr already has the status to which it is to be defined. It
is left in its current status. raddr IS CURRENTLY DEDICATED
The raddr is currently dedicated to a virtual machine. The status
is not changed froa VIRTUAL to SYSVIRT. 62 V8/370 Operator's Guide
