RSCS Generation Procedure
The AXSLINKS COPY file is a list of 1 to 64 GENLINK macro statements.
The GENLINK macro defines the attributes of a link. The first GENLINK
macro in the AXSLINKS file must contain the ID of the local RSCS station. You must also code the TYPE=driverid operand with a valid
filename on this first GENLINK macro. You should code additional
GENLINK macros, with no operands, for links you may want to define
temporarily during an operating session.
The format of the GENLINK macro is:
r------------------------------ , r , , GENLINK , ID=linkid,TYPE=driverid[,CLASS=c] , i [,KEEP=holdslot] , [ , LINE=vaddr] I [,TASK=taskname] I L J L
ID=linkid is a 1-to 8-character alphameric location ID of the remote
location to be served by the link. If this operand is not
specified, the ID defaults to "undefined."
TYPE=dri ver id CLASS=c is a ens filename of a file which is the TEXT file for the
line driver program to be used to process files for the link.
The appropriate line driver program to be specified depends on
the type of remote telecommunications facilities to be used.
The TYPE operand must be specified if ID=linkid is coded. If oper-ana1s-om-tt-e-e-ct,- TYPE defaults to uund-efined".
is the spooling class (es) of the files which can be processed
by the active link. You can specify up to four spooling
classes (single alphameric characters from A to Z and 0 to 9)
with no intervening blanks, or *, which means all spool file
classes may be processed. If the CLASS operand is not specified
r the default is KEEP=holdslot
LINE=vaddr
is a decimal number from 0 to 16 which designates the number
of virtual storage file tag slots to be reserved for exclusive
use by the link. If the KEEP operand is omitted, a default
"holdslot" value of 2 is assumed.
designates the virtual device address of a permanent
telecommunications line port to be used for processing files
on link. If the LINE operand is the default is "undefined". TASK=taskname
is a 1-to 4-character alphameric identifier. It specifies
the task name to be used by the line driver associated with
the link. If the TASK operand is omitted, the default is
"undefined". Part 3. Generating VM/370 (CP, eMS, RSCS, and IPCS) 281
