Note: that/START and /UNLQCK, /STOP and /LOCK, or /PSTOP and /LOCK are not the same. Entry of the /START, /STOP, and /PSTOP commands would normally be restricted to the master terminal but could be allowed from a remote terminal. /LOCK and /UNLOCK, relative to a physical terminal, are applicable only to the physical terminal from which the command is entered. These two commands (/LOCK and /UNLOCK), relative to logical terminals, are applicable only to logical terminals that are assigned to the physical terminal from which the command is entered. The objective of the /LOCK command is to allow the terminal user to secure a specific physical
terminal, one or more logical terminals associated with a
specific physical terminal, one or more data bases, one or more programs, and/or one or more transaction codes.
Since the formats of /LOCK and /UNLOCK are identical, only one. verb is shown in the following examples. Exception: /LOCK LTERM ALL is the only acceptable use of the parameter ALL relative to these commands.
The following /LOCK and /UNLOCK formats are acceptable:
/LOCK PTERM (Password)
This command secures the user's physical terminal. Note that no keyword parameters are acceptable, as the user can lock only his own physical terminal.
/LOCK LTERM P1 (Password), P2 (Password>
This command secures one or more logical terminals associated
with the user's physical terminal.
/LOCK LTERM ALL
This command secures all the logical terminals associated with the user's physical terminal.
/LOCK TRAN Pl (Password), P2 (Password)
This command secures one or more transaction codes.
/LOCK PROGRAM Pl (Password), P2 (Password)
This command secures one or more programs.
/LOCK DATABASE P1 (Password), P2 (Password)
This command secures one or more data bases.
2. /BROADCAST
Entry of this command would normally be restricted to the master terminal but could be allowed from any remote terminal. It is used to transmit a keyed warning or informational message to one or more
terminals. This command results in the transmission of a specific message to one or more physical terminals. The message can be only one line in length. An end-of-block key must be depr~ssed prior to the keying of the message to be broadcast. Refer to the master terminal section of the IMS/360 Operations Manual, Volume II - Machine Operations for a det·ailed description of this command.
The next two /BROADCAST commands are identical. They result in the transmission of the broadcast message to the physical terminals to which
logical terminals Pl, P2, and P3 are assigned. The following command formats are acceptable:
/BROADCAST (Password) TO LTERM Pl, P2, P3 (EOB) MSG--- (EOB)
/BROADCAST (Password) TO Pl, P2, P3 (EOB) MSG--- (EOB)
The next four /BROADCAST commands are functionally identical. They result in the transmission of the broadcast message to all the physical terminals in the system.
/BROADCAST (Password) TO LTERM ALL (EOB) MSG--- (EOB)
/BROADCAST (Password) TO ALL (EOB) MSG--- (EOB)
/BROADCAST (Password) TOPTERM ALL (EOB) MSG--- (EOB)
/BROADCAST (Password) TO LINE ALL (EOB) MSG--- (EOB)
The next two commands are functionally identical. They result in the transmission of the broadcast message to all the physical terminals located in line Pl.
134
/
/BROADCAST TO LINE Pl (EOB)
MSG-~--- (EOB) /BROADCAST TO LINE Pl PTERM ALL (EOB) MSG--- (EOB)
The following command results in the transmission of the broadcast message to relative physical terminals P2 and P3 located on line Pl.
/BROADCAST (Password) to LINE Pl PTERM P2, P3 (EOB) MSG--- (EOB)
3. /TEST
This terminal command is used to place the user's own terminal into test mode, which implies that no independent output messages will be transmitted to the user's terminal. Any input messages entered into the user's terminal will be transmitted back to the user's terminal. After the /TEST verb is entered, the user's terminal will remain in the test mode until such time as an /END command has been received from the user's terminal. Any messages which result from command processing or message switching or as the result of message processing output are enqueued for the terminal in test mode and are held until the terminal is removed from test mode. The /TEST command can apply only to the user's terminal. There are no acceptable keywords or parameters. The only acceptable format is the verb itself, as follows:
/TEST [(Password)]
4. /EXCLUSIVE
This command is used to place the user's own terminal into exclusive use or inquiry mode. The user enters this mode, through the entry of the /EXCLUSIVE verb, if he desires to enter one or more inquiries into his terminal and wants to receive only the response to his inquiries, without receiving output from other miscellaneous sources. Scheduling and queuing are allowed to continue. After the command has been
entered,· the user's terminal will remain in the inquiry mode until such time as an /END command has been received from the user's terminal. The /EXCLUSIVE command can apply only to the user's terminal. There are no acceptable keywords or parameters.
Since messages are displayed as soon as possible after queuing, the /EXCLUSIVE command is recommended for proper operation of the 2260
terminal. It will protect the screen of information from being overlaid by message switching, system messages, and messages generated by
process1ng programs initiated by other terminals while the operator is viewing a response he initiated. These messages will remain on the queue until a /END command is entered. The only acceptable format is the verb itself, as follows:
/EXCLUSIVE [(Password)]
5. /END
This command is used to terminate the mode that was originally initiated through the entry of /TEST or /EXCLUSIVE. This command can apply only to the user's terminal. There are no acceptable keywords or parameters. The only acceptable format is the verb itself, as follows:
/END [(Password)]
Page of SH20·0634·1 establish a continuing operational mode. There are no acceptable
keywords or parameters as such. One or more spaces must separate the
Message editing considerations: Destination (TRAN name or LTERM name) of the SET command is edited as the leading field of the
message. A 'blank' separator is inserted between the destination name and the text entered from the terminal, unless the first character entered from the terminal is a 'blank'.
9. /RESET
This terminal command eliminates the preset destination mode. The allowable format is: accepted. The following formats are acceptable:

L ________________ _I
where:
LTERM P1
means this command automatically accomplishes the attachment of the subpool logical terminal
pi
to the switched (dialup)communication line over which the call was received from the remote (physical) terminate
LTERM P2
means this command automatically accomplishes the logical attachment of the Inquiry logical terminal to the switched
(dialup) communication line over which the call was received from the remote (physical) terminal. Only the first four characters of the Inquiry logical terminal name are compared with the first four characters of the P2 parameter. .
For a further detail discussion of logical terminals, see Chapter 3 of the IMS/360 Operations Manual, Volume I - Systems Operation.
PTERM (Password) LTERM P1 (Password)
means the same as the above operand, but accomplishes the
attachment of all logical termin~ls associated with the subpool in which P1 exists.
11. /RDISPLAY
This command provides the ability from a remote terminal to display the logical terminal name, the relative physical terminal number, and the line number assigned as the master terminal. "The entry on the remote terminal is:
/RDISPLAY [(Password)] MASTER
