COMCHECK RDCM subcommand output

The COMCHECK RDCM subcommand formats device independent display operator console support (DIDOCS) resident display control modules (RDCMs).

To obtain the status for a RDCM, you must first find the address of its associated control block. Use COMCHECK RDCM(LIST) to find the addresses of all RDCMs in the dump. Choose an address from the list and use COMCHECK RDCM(address) to format the RDCM at that address.

If you want to view the status of all RDCMs in the dump, use COMCHECK RDCM(ALL).

The following is an example of a COMCHECK RDCM(address) report:

                    COMMUNICATION TASK ANALYSIS

                         RDCM INFORMATION

CONSOLE ID:                      0000000E
RDCM ADDRESS:                    00580C18
CONSOLE NAME:                    CON0A0
CONSOLE TYPE:                    MCS
PFK KEYS ARE OPERATIONAL:        YES
PFK BUFFER ADDRESS:              005823E8
LENGTH OF PFK BUFFER:                3096
PREVIOUS CONSOLE USE WAS:        FULL I/O CAPABILITY
STATUS DISPLAY CONSOLE:          YES
NUMBER OF LINES IN MESSAGE AREA:       28

In this example, X'00580C18' is the address of the RDCM. COMCHECK RDCM(00580C18) is the correct syntax used to obtain this report.

The following fields appear in the report:

CONSOLE ID

A 4-byte identifier that the system assigns to the console at system initialization.

RDCM ADDRESS

The address of the resident display control module (RDCM) that is being formatted.

CONSOLE NAME

A 2- through 8-character name defined in the CONSOLxx parmlib member at system initialization. If no name was specified, the console identifier appears in this field.

CONSOLE TYPE

Indicates the type of console. Possible values include:

MCS: Indicates that this is an MCS console.
SMCS: Indicates that this is an SMCS console.

PFK KEYS ARE OPERATIONAL

One of the following:

YES: PF keys are operational for this console. They are defined in the program function key (PFK) tables in the PFKTABxx parmlib member.
NO: PF keys are not operational for this console. The PF keys are not operational when a console is closed, or when a PFK table is not defined and the system cannot obtain the default PFK table.

PFK BUFFER ADDRESS

The address of the buffer containing the PFK table.

LENGTH OF PFK BUFFER

The length of the buffer containing the PFK table.

PREVIOUS CONSOLE USE WAS

The console operating mode in effect prior to a change in operating mode. It is one of the following:

FULL I/O CAPABILITY: The console can receive input, display output, accept commands, and receive status displays and messages.
STATUS DISPLAY ONLY: The console cannot accept commands; the system uses the screen to receive status displays.
MESSAGE STREAM ONLY: The console cannot accept commands; the system uses the screen to present general messages.

If no change in operating mode occurred, this field contains the mode specified at initialization.

STATUS DISPLAY CONSOLE:

One of the following:

YES: The console has status display mode capability. The system can use the screen to receive status displays.
NO: The console cannot be put into status display mode.

NUMBER OF LINES IN MESSAGE AREA

The size of the message area for this console.
