ALTER SERVICE Command
DEFAULT
allows the user to specify a default SERVICE to be automatically accessed when a
connection is established, bypassing the welcome menu and service selection
options. The default value is OFF.
Each Telserv process can have only one DEFAULT service. If an attempt is made
to specify more than one DEFAULT service the command is rejected with Telserv
error 19.
For DEFAULT ON, consider the following:

The ASSIGNED attribute should be OFF.

The RESILIENT attribute should be OFF.

The SUBTYPE attribute can be either STATIC or DYNAMIC.

The TYPE attribute should not be PRINT.
For SUBTYPE STATIC with DEFAULT ON, Telserv starts presenting the service
selection menu after all existing windows under the service are exhausted.
Subsequent connections are mapped to dynamic windows.
DISPLAY
controls the display of service names in the Service Menu and controls the amount
of SERVICE information provided on #ZSPI. This feature is provided for
SERVICEs that are security-sensitive.
LIB
identifies a local library file name to be used to launch the file-name identified in
PROGRAM. If not specified, the program is launched without a library. This
attribute is invalid if PROGRAM is not specified and is rejected with Telserv error 4.
Invalid or inaccessible file names are rejected with Telserv error 11.
OWNER
identifies the user name (group.user) that owns the service. When this attribute is
specified, a client requesting a service is authenticated and access to the service is
enforced by the Login Server. Invalid user names are rejected with Telserv error 1.
PARAM
contains a run-time parameter string up to 128 bytes to be passed in the STARTUP
message of the program being launched. You can specify any string except N/A. If
PROGRAM is not specified, this attribute is invalid and is rejected with Telserv
error 4. You can reset this attribute by setting it empty quotation marks ("").
