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

|
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
