LINE Statement Parameters

LINe line-id

Specifies the line identifier.

Line-id must be a one- through eight-character value.

Version is version-number

Qualifies the line definition with a version number.

Version-n must be an integer in the range 1 through 9999. The default is 1.

Although multiple versions of a line can exist in the data dictionary, only one version can be used by a system at runtime. If multiple ADD LINE statements specify the same line identifier, the system uses the version that appears first in the system definition.

COMpact

Indicates that redundant data in data streams transmitted to 3270-type terminals is condensed.

NOCompact

Indicates that redundant data in data streams transmitted to 3270-type terminals is not condensed.

NOCOMPACT is the default when you specify neither COMPACT nor NOCOMPACT in the LINE statement.

ENAbled

Indicates the line is enabled at system startup.

ENABLED is the default when you specify neither ENABLED nor DISABLED in the LINE statement.

DISabled

Indicates the line is not enabled at system startup.

Note: Users can override the ENABLED/DISABLED specification at runtime with the DCMT VARY LINE command.

PROTocol is

For the line type VTAMLIN only, specifies the response protocol to be assigned to the line.

DEFresp

Specifies definite response protocol is in effect for the line. Terminals associated with the line must respond with a completion status when a terminal write is requested from the DC/UCF system.

DEFRESP is the default when you omit the PROTOCOL parameter from the LINE statement.

Printers associated with the line run with definite response protocol regardless of the PROTOCOL parameter specification.

EXPresp

Specifies that exception response protocol is in effect for the line. All tasks performed on the line use exception response protocol.

Exception response protocol reduces transmission time because terminals are not required to respond with a completion status when a terminal write is requested from the DC/UCF system.

TYPe is line-type

Specifies the line type. Valid values for line-type are:

Line type

Devices supported

ASYNC

Asynchronous start/stop devices

BSC2

Binary synchronous switched or nonswitched point-to-point devices

BSC3

VTAMLU

SNA/VTAM logical units

The TYPE parameter is required to create an executable system.

additional parameters applicable to line-type

Specify optional characteristics that complete the line definition.

Depending on the value specified for line-type, one or more additional parameters may be required.

Syntax for the additional parameters applicable to each line type is presented under the heading for the line type later in this section.
