Use the DISPLAY subcommand to display: - The time of day and the date
- Summary or detailed information about SLIP traps
- Summary or detailed information about users, jobs, and address
spaces
- Summary or detailed information about outstanding requests requiring
operator action
- The status of the message processing facility (MPF)
- Information about the status of the global resource serialization
complex
- Information about the status of devices
- Summary or detailed information about page and/or swap data sets
- Summary or detailed information about the system-managed storage
configuration
The syntax of the DISPLAY subcommand of OPERATOR is:
- The specification of a d ts, d j, or d a subcommand displays exactly
the same information.
- The first two parameters on a d r subcommand are positional; the
remainder are keyword parameters. If you do not specify a positional
parameter, indicate its absence by a comma. The following specifications
illustrate the rule:
- d r,,t,msg=iea804e
- d r,,,msg=iea804e
- All parameters on a d u subcommand are positional. Therefore,
if you do not specify a parameter, indicate its absence by a comma.
The following specifications illustrate the rule:
- d u,,alloc
- d u,tp,,,nmbr
- d u,,,,nmbr
If you do not specify either nmbr or
ALLOC, nmbr defaults to 16.
If you specify ALLOC but not nmbr, nmbr defaults
to 8.
- To use the DISPLAY SMS subcommand, the Storage Management Subsystem (SMS)
must be installed and active.

- Display the local
time of day and the date; and the Greenwich Mean Time (GMT) of day
