Variables Summary

Edit online

This chapter summarizes the predefined variables supplied with CL/SuperSession.

Predefined variables are grouped into the categories shown below.

SYSccccc

Dialog Manager variables, available to all SSPL users. The variables have these characteristics:

Dialog Manager variables cannot be modified by panel input.
You can modify SYSCSR in the PROLOGUE section of a dialog to position the cursor.
An attempt to set a Dialog Manager variable, except SYSCSR, is ineffective and generates no error message.
Setting variable SYSKEY is possible, but not recommended.

ZTBccccc: Table services variables.

The following tables list the predefined variables. The column headings use the following abbreviations:

LEN: Specifies the length of the variable in bytes. A LEN of VAR indicates a variable length. Fixed-length variables are left-justified and blank-padded.

R/W: Indicates whether IBM® recommends that the variable be set (W), used (R), or both (R/W).

Table 19. Dialog Manager Variables
VARIABLE	LEN	R/W	DESCRIPTION
SYSAPPL	8	R	ACB name of the current dialog process.
SYSCPUID	208	R	CPU ID(s), taken from the z/OS® PCCACPID field(s). Expressed as 16 12-character fields, separated by a blank. If a CPU is not present, its field is blanks.
SYSCSR	8	R/W	Cursor position, specified by the actual name of an input variable. CL/SuperSession positions the cursor at the start of the input field (in the body of the dialog) associated with that variable. An alias name cannot be used. The field must be modifiable.
SYSCVTFX	256	R	The 256-byte z/OS CVT prefix.
SYSDATE	8	R	System date in the format defined by the DATEFMT function.
SYSFDATE	8	R	System date containing a 4-digit year in the format defined by the DATEFMT function.
SYSDLG	8	R	The name of the currently executing dialog. Note: The CSTACK dialog function may be used instead of the SYSDLG variable.
SYSDOW	1	R	The day of the week, expressed as a number. 0 is Sunday, 1 is Monday, and so forth.
SYSJDATE	8	R	The current date, expressed as an IBM-format Julian date, `yyyy.ddd`, where "£yyyy" is the 4-character year, and "ddd" is the 3-character day of the year with leading zeros as needed. For example, `2018.015`.
SYSJOB	8	R	CL/SuperSession jobname.
SYSKEY	5	R	The Attention Identifier (AID) key used to complete the last panel input, or the trigger AID key used to invoke the current dialog. ATTN This value is valid for SNA terminals only. SYSKEY will be set to this value if, while a dialog panel is displayed and waiting for input, the terminal user presses the Attention key. CL/SuperSession receives an SNA SIGNAL request unit and converts this into the ATTN indication of the SYSKEY variable. CLEAR The Clear key. Enter The Enter key. PAn Program Attention key (n = 1 to 3). PEN The Light Pen or Cursor Select key. PFn Program Function key (n = 1 to 9). PFnn Program Function key (nn = 10 to 24). SYSRQ This value is valid for SNA terminals only. SYSKEY will be set to this value if, while a dialog panel is displayed and waiting for input, the terminal user performs a double Alt-SysRq operation on the keyboard. The first Alt-SysRq will switch the terminal logical unit from the LU-LU session (the session with CL/SuperSession) to the SSCP-LU session. The user can then interact with the SSCP, to enter a connectivity test command, for example. If the terminal user performs a second Alt-SysRq operation, the terminal logical unit will return to the LU-LU session and, in normal circumstances, will transmit a special SNA LUSTAT request unit to CL/SuperSession. Secondary LUs may also send status code 082B in an LUSTAT request meaning that the device component is available but the presentation space integrity is lost. CL/SuperSession converts this LUSTAT into the SYSRQ indication of the SYSKEY variable. TOT Time limit for a screen to display without user input has expired.
SYSLMODE	8	R	VTAM® logmode entry name in effect for the users physical terminal session.
SYSPARM	VAR	R	The main cases are: In the virtual sessions initial dialog, &SYSPARM is the value of the session ID being initialized. In a trigger dialog, &SYSPARM is the value of the parameter defined with VSSTRIG for the trigger, or supplied by the user when the trigger is invoked. In immediate broadcast target dialog, &SYSPARM is the text of the message sent by an operator via the IMBRCST function. When a termination dialog executes, &SYSPARM contains the session ID of the session being terminated. In all other cases, &SYSPARM is the optional parameter value passed from the calling dialog.
SYSPROC	8	R	CL/SuperSession PROC stepname.
SYSPRSVC	12	R	Presentation services field (from the BIND image) for the physical terminal session. This field is in binary format. See "Logical Unit Presentation Services" in IBM's :citACF/VTAM Programming manual.
SYSNET	8	R	VTAM SLU Network Name of the users terminal. If the name is less than 8 characters, it is left-justified, blank-padded.
SYSRC	VAR	R/W	The string, typically a return code, set by RETURN (when used to return from a dialog) or EXIT.
SYSSEED	4	R/W	The seed used by the RANDOM dialog function.
SYSSMFID	4	R	SMF system ID of the host processor on which the CL/SuperSession address space is running.
SYSSTEP	8	R	CL/SuperSession JOB stepname.
SYSTERM	8	R	VTAM logical unit name of the users terminal. If the name is less than 8 characters, it is left-justified, blank-padded.
SYSTIME	8	R	System time in 24-hour format (hh:mm:ss).
SYSTIMEO	N/A	R	Indicates whether (null) or not (not null) the executing dialog has been given control by ON ' TIMEOUT' .
SYSTRIG	VAR	R	The trigger phrase, if any, used to invoke the current dialog.
SYSTRPM	VAR	R	The default parameter, if any, defined with VSSTRIG for the currently executing trigger.
SYSVAR	8	R	The name of the panel input field the cursor was in when the user pressed an AID key.
SYSDDLD	VAR	R	Load library DDNAME.
SYSDDPRM	VAR	R	Initialization library DDNAME.
SYSDDCMD	VAR	R	Command list library DDNAME.
SYSDDPNL	VAR	R	Panel library DDNAME.
SYSDDHLP	VAR	R	Help library DDNAME.
SYSDDLOG	VAR	R	Log dataset DDNAME.
SYSDDSNP	VAR	R	Snap dump dataset DDNAME.
SYSDDIN	VAR	R	Startup parameters dataset DDNAME.

Table 25. Table Services Variables
VARIABLE	LEN	R/W	DESCRIPTION
ZTBCSFLD	8	R/W	Specifies the field name in the model set where the Dialog Manager places the cursor. If this variable is specified, ZTBCSROW must also be specified. If no field name is supplied, the Dialog Manager uses the first field in the model set. (A model set is a template used by TBDISPL for displaying rows.)
ZTBCSOFF	8	R/W	Specifies the offset within the field where the Dialog Manager places the cursor.
ZTBCSROW	8	R/W	Specifies the table row number that the cursor will be placed in. If no row is specified or the row is not in the current display, the Dialog Manager places the cursor in the first row on the display.
ZTBHAND	8	R	Contains the handle of the table used with the TBDISPL function. Used from within the dialog executed by TBDISPL. (Not available in the dialog INIT section.)
ZTBMARK	VAR	R/W	Specifies the string that is to appear at the end of a TBDISPL display. When ZTBMARK is null, a standard message is displayed at the bottom of a table: BOTTOM OF DATA
ZTBMARKA	VAR	R/W	Controls whether an attribute is placed before the ZTBMARK line on the TBDISPL. If ZTBMARKA is null, an attribute of HIGHLIGHT PROTECTED is used; any other value causes no attribute to be placed on the field.

ZTBSEL	8	R	Specifies the number of rows pending to be processed.
ZTBSIZE	8	R/W	Specifies the maximum number of model sets on the most recent display. (A model set is a template that TBDISPL uses to display rows.) This variable limits the number of rows displayed, excluding titles and blank lines. If it is zero, the Dialog Manager displays as many rows as possible and sets ZTBSIZE to that value. Note: If a TBDISPL dialog invokes another TBDISPL dialog, there may be interference between the two and the display could be truncated. To eliminate the problem, explicitly code SCOPE(LOCAL) for ZTBSIZE.
ZTBTROW	8	R	Contains the top row number of the most recent TBDISPL display.
ZTBXRC	8	R	Contains extended return code information when some Table Services dialog functions fail. See Table Services Extended Return Codes (ZTBXRC) for more information.
