The easiest way to see what works - try the commands.
What does a D D,O command show?
What does a DD T,AUTODSN=ALL
DD ALLOC={ACTIVE|INACTIVE}
ALLOC=ACTIVE
Dump data sets are automatically allocated when a dump is requested. Any of
the resources that have been defined by the DUMPDS ADD command as available for
automatically allocated dump data sets are used. If no automatic allocation
resources are defined, the system issues message IEA799I and writes the dump to
a pre-allocated dump data set on its list of SYS1.DUMP data sets. If no
pre-allocated dump data sets are on the system's list of SYS1.DUMP data sets,
then message IEA793A is issued requesting operator intervention. The requested
dump is kept in virtual storage until an automatic allocation resource is
defined, a pre-allocated dump data set is made available either by allocating a
new one or clearing an existing one, or the dump is deleted either by operator
request or expiration of the CHNGDUMP MSGTIME parameter.
The books show what you can use for symbols in the name. TinyURL:

Symbols reserved for system use. When you define additional system symbols in
the IEASYMxx parmlib member (see “Step 5. Create an IEASYMxx parmlib member” on
page 44), ensure that you do not specify the names of the following system
symbols, which are reserved for system use:
&DATE
&DAY
&HHMMSS
&HR
&JDAY
&JOBNAME
&LDATE
&LDAY
&LHHMMSS
&LHR
&LJDAY
&LMIN
&LMON
&LSEC
<IME
&LWDAY
&LYR2
&LYR4
&LYYMMDD
&MIN
&MON
&SEC
&SEQ
&SID
&SYSCLONE
&SYSNAME
&SYSPLEX
&SYSR1
&SYSUID
&TIME
&WDAY
&YR2
&YR4
&YYMMDD
&SYSALVL
The comments in the quotes would be ignored. Same thing would happen if you
entered it from the console.
Summary:
DD ALLOC=ACTIVE
DD ADD,SMS=( [DATA|D=[dataclas]][,MGMT|M=[mgmtclas]][,STOR|S=[storclas])
DD NAME=some_data_set_mask_here
D D,O
You can control your System Dump Datasets through ACS code or your can specify
the SMS classes you want Dumps to use in the DD ADD,SMS command.
