Appendix B Managing the BRW Tutorial
Managing the Tutorial
This appendix describes the account, groups, and files used with the
tutorial in this manual. It describes how the tutorial is set up and
gives hints on how to manage the tutorial if many students wish to use
the tutorial at the same time.
Who Should Read This Appendix?
The person who reads this should be familiar with the HP3000, and,
ideally, familiar with BRW. No special knowledge is assumed for those who
take the tutorial.
Store the Tutorial Files
Before performing the tutorial for the second time, store the tutorial
files so that you have a clean copy of them. Store the fileset:
@.@.ITF3000
Then, if a student corrupts a file, you can restore it from your store
tape. The tutorial files use approximately 0.4Mb.
How the Tutorial is Set Up
The tutorial files is set up automatically when the MIT tape is
installed. The tutorial files are held in account ITF3000. Four groups
are used for the tutorial files:
* PUB.ITF3000. This group contains the database TOYDB and the
BRWDIC file.
* BRWSPEC.ITF3000. This group contains the specification files of
the three example solutions: SOLUTN1, SOLUTN2, and SOLUTN3.
* BRWEXEC.ITF3000. This group contains the execution files of the
example solutions: SOLUTN1, SOLUTN2, SOL3DIR, and SOL3SMN. These
are in native mode.
* This group holds the printfiles (example printouts directed to a
disk file) for the example solutions: SOLUTN1, SOLUTN2, SOL3DIR1,
SOL3DIR2, SOL3SMN1, SOL3SMN2, and SOL3SMN3.

Other Changes to Account ITF3000
The tutorial installation does not otherwise affect account ITF3000, that
is, no passwords are set and no new users are added. The files' and
database's creator is MGR.
You can add users or passwords to the account ITF3000, and to its groups
and users, but see "Default User" .
Note that account ITF3000 can be used by other training courses, for
example, LearnDESK (the HPDESK training).
Default User
The tutorial assumes that there is only one student running the tutorial
at a time, and that this student has logged on as follows:
: HELLO MGR.ITF3000,BRWSPEC
That is, the student will work in group BRWSPEC, as user MGR. Whenever
prompts for user, group, and account are shown in the text, the
appropriate entries are: user MGR, in group BRWSPEC, and account
ITF3000.
If the student does not log on as MGR, the actual prompts may differ
slightly from the printed examples.
Managing Multiple Users of the Tutorial
The tutorial assumes that there is only one student running the tutorial
at a time. More than one student can run the tutorial, however, this
may cause problems. For example, if two students wish to run
report 2, only one of them, can create a specification file called
CUSTREP2.BRWSPEC.ITF3000. The following are some suggestions for
handling multiple users of the tutorial.
* Arrange for each new student to use different file names, perhaps
by replacing the second four letters of each report ("CUST") with
their initials. Note that these new filenames will then appear in
on-screen in place of CUSTREP1, CUSTREP2, and so on.
* Restore the tutorial files in other accounts on the same system.
Then, tell the student using that other account to use the
account's name whenever instructed by the tutorial to use account
ITF3000.
Managing Students' Files
Once a lesson has been completed, delete the specification and execution
files so that later students can use the same filenames.
