IMAGE specifies an existing boot image name to be modified or replaced. If the specified boot image does not
exist, an error occurs.
FILE specifies a file name to replace the designated boot image. If it is not fully qualified with group and
account name, it defaults to the current group and account. If the specified file does not exist, an error occurs.
TYPE specifies the boot image type. The various types are defined as follows:
DISC Specifies that the file is applicable to a disk boot only.
TAPE Specifies that the file is applicable to a tape boot only.
BOTH Specifies that the file is applicable to both disk boot and tape boot.
To modify or replace a boot image file name, enter the command, image name, and fully qualified file name.
Here are two examples.
sysfile>RBOOT imagename TYPE=DISC
sysfile>RBOOT imagename filename DISC
Use the SHOW command to display the boot image file names maintained by the system.
Configuring a Message Catalog
The RCAT command (abbreviated RC) configures the message catalog to be used on the target system. RCAT has
the following parameter:
RCAT (RC) [NAME =] filename
The system message catalog contains all the system and subsystem messages. It is retained under a known
file name (CATALOG.PUB.SYS).
NAME specifies a catalog file name. If the name is not fully qualified, it defaults to the current group and
account.
To replace the default catalog name CATALOG.PUB.SYS with a new catalog name, enter RCAT and the fully
qualified file name:
sysfile>RCAT filename.group.account
If the new message catalog file was not previously created, an error occurs.
NOTE For information on how to modify an existing message catalog, refer to the Message Catalogs
Programmer’s Guide.
Replacing a CMSL Segment

RCMSL (RCM) [SEG =] segment-name
[FILE =] filename
[MODE = S ]
[ C ]
[ P ]
[ U ]
SEG specifies a new segment name of maximum eight characters. If a nonexistent segment name is specified,
an error occurs.
