TSO Commands

Clemson Univ. is legitimate propetary of this page, I only put this page in my home for better reference.

The following is a list of TSO commands and a brief description of the use of each. Most of these commands have abbreviated aliases which are shown in all caps. For further information on how to use these commands, type HELP (or H), followed by one or more blanks, followed by the name of the command or its alias.

#

Invokes a command processor located in a load library allocated to file CMDLIB.

AD

Puts a discrete RACF profile on a specific dataset.

ALias

Gives alias names to members of partitioned datasets. Because use of this command on a load library produces unpredictable results, it is advisable to use LINK in this situation.

ALLOCate

Allocates or creates temporary datasets, associates a file name with a data set, or designates files for output.

ATTRib

Defines DCB parameters to be used with a subsequent ALLOCATE command.

CALL

Executes load modules (programs already compiled and link edited) at the terminal.

CHANGE

Changes the name of a member of a partitioned dataset which is allocated SHR (allocated to more than one user or job at a time). Use of this command on a load library produces unpredictable results.

CODE

Produces an explanation of system completion codes and FORTRAN error codes.

CONCAT

Concatenates (combines) two or more datasets under a single file name. The ALLOCATE command can also perform this function.

DCF

Invokes IBM's Document Composition Facility (DCF) text formatting program.

DD

Deletes the RACF profile for a dataset

DELete

Deletes a data set or a member of a partitioned dataset.

DISASSEM

Disassembles a load module.

DUPlicat

Prints the contents of a dataset.

Edit

Invokes the IBM line editor.

EXec

Executes a clist (command procedure).

FREE

Frees data sets and files allocated to the user's TSO session and deletes attribute lists.

Free All

Frees all data sets and files allocated to the user's TSO session except those allocated by the LOGON procedure.

GI

Invokes ISPF (Interactive Systems Productivity Facility).

HELP

Obtain help about TSO commands.

HELPJCL

Lists the statements necessary to use a catalogued procedure.

HEX

Performs hexadecimal addition or subtraction at the terminal.

IOF

Allows you to show the status of jobs and to browse, print, or cancel the output from jobs.

JOURNAL

List amount of money charged to an account or computer ID.

KERMIT

Transfer a file between a microcomputer and the OS/390 mainframe system.

LD

Lists the RACF profile for a dataset.

LINK

Executes the linkage editor from the terminal.

List

Lists the contents of a sequential dataset or of a member of a partitioned dataset.

LISTAlc

Lists the names of datasets and files currently allocated to the user.

LISTBc

Lists messages saved in the broadcast dataset.

LISTCat

Lists the names of catalogued datasets.

LISTDs

Lists DCB attributes of a dataset or of the members of a partitioned dataset.

LISTHEX

Lists the contents of a dataset in hexadecimal.

LISTLOAD

Lists the names of members of a load library, along with the size and attributes of each load module.

LOADgo

Executes the loader, which loads an object deck (compiled program), resolves external references, and executes the program, from the terminal.

LOGOFF

Ends a TSO session.

LOGON

Initiates a TSO session.

PDS

Access and manipulate the directory and members of a PDS (partitioned dataset).

PE

Provides another user RACF access to specified datasets.

PROFile

Defines certain user characteristics which control the flow of information to and from the user's terminal.

REName

Changes the name of a sequential dataset, of a partitioned dataset, or of a member of a partitioned dataset, or creates an alias for a member of a partitioned dataset. This will not work for load modules (DO NOT rename a permanent dataset).

Run

Compiles, loads, and executes the source statements in a data set.

SAS

Invokes interactive SAS.

SCAN

Searches a load module for a specified hexadecimal string.

SCRatch

Deletes a member of a partitioned dataset.

SEnd

Sends messages to other TSO users.

SHow

Shows the status of a particular job, the status of all jobs belonging to the user, the number of jobs awaiting execution, or the different output files for a particular job.

SIZE

Displays amount of space allocated to a dataset and how much of that space is used.

SPACE

Lists the names of disk packs available to house temporary datasets and how much space is available on them.

SPEAKEZ

Invokes the SPEAKEASY processor.

SUBmit

Submits a job from the terminal (NOTE: SUB is the alias for this command).

TERMinal

Defines terminal characteristics (such as number of lines per screen).

TEST

Debugs assembler language programs at the terminal.

TIME

Displays cumulative CPU time, cumulative session time, service units used, local time of day, and today's date.

TYPE

Prints a message at the user's terminal.

US

Lists all TSO users currently logged on and displays the number of such users.

WhatLine

Lists all TSO users currently logged on together with their line numbers and terminal names.

WHEN

Tests the system return code from a previously executed command.

WHOGOT

Determines to what user or to what job a particular dataset is allocated.

?

Displays additional information if a user has just received a message terminating with a plus sign (+).
