Parsing Algoithms and User Exit Procedures

User Exits

Two exits have been added to SNA NRJE to facilitate job management

and output management operation. One exit calls a customer’s

procedure that decodes the host banner (separator page) and informs

NRJE of the host job number for the data set. A separate exit

procedure can be speciﬁed for each logical writer.

A second exit passes all console data to a customer’s procedure that

parses the host “Job Received” messages sent by the host to the remote

console when a job is submitted.

NOTE

If an exit procedure is not speciﬁed, NRJE uses its own internal parsing

algorithms to decode banners and “Job Received” messages. The exit

procedures are not necessary unless the host has been modiﬁed to send

nonstandard banners or console messages.

Conﬁguration

These two steps must be performed to conﬁgure SNA NRJE to access

an exit procedure:

1. Install the procedure segment from the USL ﬁle into SL.NRJE.SYS.

2. Identify the name of the console exit procedure in the NMMGR

Workstation Data Page 2 screen and the banner decode procedure(s)

in the NMMGR Writer Data Screen. These exit procedures are

conﬁgured differently. Conﬁguring a banner exit as a console exit

can cause a system failure.

CAUTION

NRJE exits grant privileged mode access to system resources. Improper

installation and conﬁguration of user exits can cause a system failure.
