3. In cases where multiple storage ranges or limits are specified on
one command line and the line contains errors, coa.and execution
successfully processes all correct operands to the encountered
error. The encountered error and the remainder of the co •• and line
is rejected and an appropriate error aessage is displayed. 4. For default operand values (the beginning and ending of storage) to
be applicable, at least one operand must be specified.
5. In attached processor applications, the PSI values for the main and
the attached processor are not located at absolute page zero but
are displacements froll it. Therefore, prefixing the hexadecimal
location with an M or N will add the hexadecimal value to the
displacellent of the location of the assigned PSI for the designated
processor; for example: DMCP .40.8 Dumps the CSi of the main processor
n78-7f Dumps the I/O new PSi of the attached processor. Is the dump proceeds, the following message appears at the terminal indicating that the dump is continuing from the next 64K boundary: DUMPING LOC hexloc
where "hexloc" is the segment (64K) address for the dump continuation,
such as 020000, 030000, 040000. If the user signals attention on the terminal the above message is displayed, the dump ends. COftMIND COMPLETE indicates normal completion of the dump.

DRAIN Use the DRAIN command to stop spooling operations on the specified real
unit record devices after the file currently being processed has
coapleted. This command brings the spooling system or a specified
.device to a controlled halt, or halts the activities on a device whose
spooling status is to be changed. For exaaple, all unit record devices
are usually drained before system shutdown, and a printer must be
drained before the contents of the UCS printer buffer are changed. A device is drained i.mediately if it is not active when the DRAIN
command is issued; otherwise, it is drained when processing of the
current file has completed. A drained device can be restarted by the
START command. If START is issued to a device before draining is
complete, the device does not enter the drained status but continues
processing. The format of the DRAIN command is:
