LINES

The LINES macro is used to specify the numbers and types of non-SNA communication lines to be attached to the system or directly to the channel for local 3272s.

The number of lines defined in the LINES macro must agree with the number specified during non-SNA communications generation. See Non-SNA Communications. You should also refer to the LINEQ macro listing before coding this macro.

If the system being generated consists of only SNA communications lines, then you do not need to code this macro; SIP will automatically assign the default values shown below.

The LINES macro is only to be coded when generating a base only system or when generating the basic subsystem in a multiple database function (MDBF) environment.

Format




Note:
The following parameters are only used for synchronous line control (SLC) lines. If entered, N2703 in NETWK must not equal zero.

SLCAI=0|n
Number of synchronous link control AI lines attached to the EP communication controllers. If entered, SYNCLK macro must be coded.

PSLNS=0|n
Number of SLC pseudo ALC lines to be assigned to the system. If this field is entered, NLINK parameter in SYNCLK must not equal zero.
Note:
The following parameters are only used for BSC lines. If entered, N2703 in NETWK must not equal zero.

BSCLN=0|n
Number of bisynchronous lines to be attached to the EP communication controllers.

BSCOP=(p1, p2,...pn)
This optional keyword specifies options for BSC lines. The parameter list may be coded in any order and each entry must be separated by a comma. The valid BSCOP parameters (p1,p2,...pn) are:

CT
The system will be a BSC control station

EB
BSC EBCDIC code will be used

MP
BSC multipoint lines will be included

PP
BSC point to point lines will be included

US
BSC USASCII code will be used

BSCDRPS=n
The total number of BSC drops on the system. A BSC drop is defined as the following:
  1. A point-to-point BSC line connecting a processor to a processor is defined as 1 drop.
  2. A multipoint BSC line with two processor stations attached to it is defined as 2 drops.
  3. A point-to-point BSC line connecting a processor to a processor station is defined as 1 drop.

Default is as follows:

  1. If BSCOP=MP is coded then the number of BSC drops will equal the total number of BBSAT macros coded multiplied by the total number of BSC lines (BSCLN).
  2. If BSCOP=PP is coded and not MP then the total number of BSC drops will default to the number of BSC lines coded in the BSCLN parameter.
Note:
The NLSLC parameter is only used for IBM 3270 local lines. If entered, the D3270 parameter in NETWK must not be NO.

NLSLC=0|n
Number of 3270 local lines.
Note:
The MINLS parameter applies to all of the LINES macro parameters.

MINLS=20|n
A valid hexadecimal number representing the first symbolic line number. For more information about how MINLS is used, see the LNSY parameter description of the SKLNG macro in SKLNG.

Examples

A system contains 9 BSC lines and there are a total of 35 point-to-point and multipoint drops on the BSC lines. The LINES macro can be coded as follows:

LINES   BSCLN=9,BSCOP=(MP,PP,CT,EB,US),   X
       BSCDRPS=35
