TERMINAL command operands

LINES(integer) | NOLINES

LINES(integer) ¹: specifies an integer from 1 to 255 that indicates you want the opportunity to request an attention interruption after the specified number of lines of continuous output has been directed to your terminal.
NOLINES ¹: specifies output line count is not to be used for controlling an attention interruption. This is the default condition.

SECONDS(integer) | NOSECONDS

SECONDS(integer) ¹: specifies an integer from 10 to 2550 (in multiples of 10) to indicate that you want the opportunity to request an attention interruption after a number of seconds has elapsed during which the terminal has been locked and inactive. If you specify an integer that is not a multiple of 10, it is changed to the next largest multiple of 10.
NOSECONDS ¹: specifies elapsed time is not to be used for controlling an attention interruption. This is the default condition.

INPUT(string) | NOINPUT

INPUT(string) ¹: specifies the character string, if entered as input, will cause an attention interruption. The string must be the only input entered and cannot exceed 4 characters in length.
NOINPUT ¹: specifies no character string will cause an attention interruption. This is the default condition.

BREAK | NOBREAK

BREAK: specifies, for IBM® 3767 and IBM 3770 terminals, the system can interrupt your input. For other terminals, it specifies that your terminal keyboard is to be unlocked to allow you to enter input whenever you are not receiving output from the system. The system can interrupt your input with high-priority messages. Because use of BREAK with a terminal type can result in loss of output or error, check with your installation system manager before specifying this operand.
Note: If a command processor for a display device is operating in full-screen mode, VTAM treats the device as if it were operating in NOBREAK mode. For a more detailed description, see z/OS TSO/E Programming Services.
NOBREAK: specifies, for IBM 3767 and IBM 3770 terminals, the system is not allowed to interrupt you (break in) with a message when you are entering data. For other terminals, it specifies that your terminal keyboard is to be unlocked only when your program or a command you have used requests input.
The default for the BREAK/NOBREAK operand is determined when your installation defines the terminal features.

TIMEOUT | NOTIMEOUT

TIMEOUT ¹: specifies your terminal keyboard will lock automatically after approximately 9 to 18 seconds of no input.
NOTIMEOUT ¹: specifies your terminal keyboard will not lock automatically after approximately 9 to 18 seconds of no input.
The default for the TIMEOUT/NOTIMEOUT operand is determined when your installation defines the terminal features.

LINESIZE(integer)

specifies the length of the line (the number of characters) that can be printed at your terminal. The integer must not exceed 255. LINESIZE is not applicable to the IBM 3270 display stations. The default values are:

Teletype 33/35: 72 characters
IBM 2741 Communication Terminal: 120 characters
IBM 3767 Communication Terminal: 132 characters
IBM 3770 Communication System: 132 characters

If LINESIZE (80) is coded with a RECFM equal to U, then the line is truncated. The byte truncated (the last byte) is reserved for an attribute character.

If you use LINESIZE to adjust the line length of an LU1 device, the line length defaults to zero.

CLEAR(string) | NOCLEAR

CLEAR(string) ¹: specifies a character string, if entered as input, causes the screen of an IBM 3270 Display Station to be erased. The string must be the only input entered and cannot exceed 4 characters in length.
NOCLEAR ¹: specifies that you do not want to use a sequence of characters to erase the screen of an IBM 3270 Display Station. This is the default condition.

SCRSIZE(rows,length)

specifies the screen dimensions of an IBM 3270 Display Station, an LU2 device with VTAM, and a Network Terminal Option (NTO) terminal. When you specify the SCRSIZE operand, you must use the LINESIZE operand to get continuous writing on a NTO terminal.

If you are running under Session Manager, the system ignores SCRSIZE.

rows: specifies the maximum number of lines of data that can appear on the screen.
length: specifies the maximum number of characters in a line of data displayed on the screen.

Standard screen sizes (in rows and length) are:

6,40
12,40
12,80
15,64
24,80
27,132
32,80
43,80

The default values for the screen sizes are determined when your installation defines the terminal features.

TRAN(name) | NOTRAN

TRAN(name)

specifies a load module that contains tables used to translate specific characters you type at the terminal into different characters when they are seen by TSO/E. Conversely, when these characters are sent by TSO/E to the terminal, they are retranslated. Translation of numbers and uppercase letters is not allowed.

Character translation is especially useful when you are using a correspondence keyboard and would like to type the characters: <, >, │.

They are not available on a correspondence keyboard. For example, translation tables make it possible for you to specify that when you type the characters: [, ], !.

TSO/E interprets them as <, >, and |.

NOTRAN

specifies no character translation is to take place.

CHAR | NOCHAR

CHAR: specifies one or more pairs of characters, in either hexadecimal or character notation, that replace characters in the translation tables specified by TRAN(name) or in the default translation tables. When the default translate is used, all unprintable characters are set to blanks. The first character of the pair is the character typed, printed, or displayed at the terminal. The second character is the character seen by TSO. Translation of numbers and uppercase letters is not allowed. Do not select characters that might be device control characters.
NOCHAR: specifies all character translations previously specified by CHAR are no longer in effect.

¹ Not supported with terminals that use VTAM®.
