&MAXCC

Maximum value of the return code.

&SYS#CC

Completion code of a completed job. It is set when an ENDJOBNAME event is raised.

&SYS#EVENT

&SYS#EVTNO

Stores the event that corresponds to the event number specified when an event occurs if multiple values are specified in a single operand in the WAIT command.

&SYS#FMSG

Stores the entire outputted message. Set when a MESSAGE event or MSGID event is raised.

&SYS#JN

Job name of the completed job. Set when an ENDJOBNAME event is raised.

&SYS#MSG

Stores the main text of the outputted message. Set when either a MESSAGE event or an MSGID event is raised.

&SYS#PFX

Stores the identifier of the outputted message. Set when either a MESSAGE event or MSGID event is raised.

&SYSASIS

&SYSCONLIST

&SYSDATE

Current date in the mm/dd/yy format.

&SYSDVAL

String in which the user recently entered to the terminal.

&SYSENV

&SYSFLUSH

&SYSICMD

Name of a command procedure. Used only when a command procedure is not executed explicitly by using the EXEC command in an implicit execution.

&SYSNEST

&SYSPCMD

A recently executed TSO command (excluding parameters). The default value is EXEC.

&SYSPREF

Prefix of the data set name.

&SYSSCAN

Specifies the maximum number of times for scanning (the process of substituting a symbol parameter with a value) to be performed before executing each command procedure command.

&SYSSDATE

Current date in the yy-mm-dd format.

&SYSSTIME

Current time in the hh:mm format.

&SYSSTOP

Maximum number of commands that can be executed in a command procedure.

&SYSSYMLIST

&SYSTIME

Current time in the hh:mm:ss format.

&SYSTMID

Name of the currently connected terminal.

&SYSUID

TSO session user ID.

&DATATYPE (expr)

Returns NUM if the result of the expression expr is a number, and returns CHAR if it is a string.

&EVAL (expr)

Returns the operation result of the formula expr.

&LENGTH (expr)

Returns the character length of the operation result of the expression expr.

&NRSTR (expr)

Substitutes the symbol parameters of expression expr, but returns the results without a superposition substitution. Does not execute mathematical operations.

&STR (expr)

Substitutes the symbol parameters of expression expr and returns the result of processing built-in functions. Does not execute mathematical operations.

&SUBSTR (from:to,str)

Returns the substring extracted from the "from" position to the "to" position of the string str. Only extracts one character from the "from" position if "to" is omitted.

&SYS#EPRM (eprm)

Returns the value of the virtual parameter eprm. For information about virtual parameter configuration, refer to Chapter 1.

&SYSDSN (d)

Checks the status of the data set "d", and returns "OK" if in a usable status and returns an error message if otherwise.

&SYSINDEX (needle,haystack,start)

Returns the position of the string needle in the string haystack. Finds the needle in the entire haystack if "start" is "0" or omitted. If "start" is a positive number, then finds the needle from the starting character of the haystack. Returns 0 if the needle is not found.

&SYSNSUB (level,expr)

Substitutes the symbol parameter of the expression expr, but substitutes it in the maximum level of times.

ATTN

Sets the interrupt handler. For syntax check only.

CLOSFILE

Closes the data set.

CONTROL

Specifies options related to executing command procedures.

DATA-ENDDATA

Separates the TSO command and the screen output data area.

DO-END

Repeatedly executes one or more command procedure commands.

ERROR

Sets the error handler.

EXIT

Stops the execution of a command procedure and returns control to the parent command procedure.

GETFILE

Reads a record from a data set.

GLOBAL

Declares a symbol parameter shared between nested command procedures.

GOTO

Branches to a specified location.

IF-THEN-ELSE

Executes different actions according to specified conditions.

INDATA

Specifies the data set where the screen output data will be stored. For syntax check only.

OPENFILE

Opens a data set.

PROC

Defines the symbol parameter received from the parent command procedure.

PUTFILE

Writes a record in a data set.

READ

Stores the data received from the user through the terminal in the symbol parameter.

READDVAL

Stores the information of the control variable &SYSDVAL in the specified symbol parameter.

RETURN

Returns control to the command procedure command that is after the command procedure command in which an error is raised.

SET

Stores a value in the symbol parameter or a control variable.

TERMIN

Passes control to the terminal in order to receive user input. For syntax check only.

WRITE/WRITENR

Displays a string on the terminal.
