TSO Keywords

A list of the TSS keywords used with TSO default data fields and a brief description appear next. The TSS ADD/REMOVE and REPLACE command functions are used to accommodate these items in the CA Top Secret environment.

TSOLACCT

The one‑ to 40‑character logon account number. Account numbers are also TSO‑related resources and the user must be permitted to any account number with which he attempts to log.

TSOCOMMAND

The one‑ to 80‑character logon command. This command is executed by TSO immediately after logon (assuming successful completion). The logon command is not required and the user need not fill it in at logon time if blank. The user must have the appropriate security permissions (that is, PROGRAM, LCF) as warranted for the command chosen. For example, if TSOCOMMAND(TEST) is chosen, the userid must have PROGRAM and LCF authority to the TSO TEST command if they would normally be required. Using TSOCOMMAND does not exempt the user from normal security checking.

TSODEST

The one‑ to eight‑character destination name for the session output. It is not required for, and cannot be changed at, logon.

TSOHCLASS

The one‑character hold class. It is not required for, and cannot be changed at, logon.

TSOJCLASS

The one‑character job class. It is not required for, and cannot be changed at, logon.

TSOMCLASS

The one‑character message class. It is not required for, and cannot be changed at, logon.

TSOSCLASS

The one‑character sysout class. It is not required for, and cannot be changed at, logon.

TSOLPROC

The one‑ to eight‑character logon procedure name. Procedure names are also TSO‑related resources and the user must be permitted to any procedure name with which he attempts to log on. Also, the user must specify a procedure name to log on, and have security permissions to any data sets allocated by that chosen procedure name. If this value is not set with a TSS command, he must fill in this field on the screen at logon time.

TSOLSIZE

The one‑ to seven‑numeric character region size at logon. The value chosen denotes the region size, in kilobytes, and can be changed at logon.

TSOMSIZE

The one‑ to seven‑numeric character representing the maximum region size, in kilobytes, which can be specified at logon by the user. (That is, the region size at logon must be less than or equal to this value.)

TSOOPT

The logon options that include these values: MAIL/NOMAIL, NOTICES/NONOTICES, and OIDCARD/NOOIDCARD. These values may be coded on a TSS command; the user can change the options by menu selections at logon time.

TSODEFPRFG

The one‑ to three‑numeric character representing the performance group number, whose value can range from 1 to 255. Performance groups are used by the system to determine allocation of system resources (for example, CPU time) based on installation‑defined criteria. Performance group numbers are also TSO‑related resources and the user must be permitted to any group number with which he attempts to log on. A performance group number is not required, and cannot be changed at logon.

TSOUDATA

The four‑character installation‑defined data whose values range from 0 to 9, and A to F. This data is used by installations for any chosen purpose. It is not alterable by the user at logon time and not required for, and cannot be changed at logon.

TSOUNIT

The one‑ to eight‑character unit (device) name for dynamically‑allocated data sets. The name must be a defined generic unit class name at the installation. This field is not alterable by the user at logon and is not required for successful logon.
