gtps4m2y | System Generation |
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:
- A point-to-point BSC line connecting a processor to a processor is defined
as 1 drop.
- A multipoint BSC line with two processor stations attached to it is
defined as 2 drops.
- A point-to-point BSC line connecting a processor to a processor station is
defined as 1 drop.
Default is as follows:
- 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).
- 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
