Hello,

The experiment,

I've now tried out the programs successfully. The distribution
contained,

  - somesympts.txt

    Some data in a textual format.

  - gensympt.bet

    A beta program that reads the data from 'somesympts.txt' and
    inserts it into a PostGreSQL database.

  - listsympt.bet 

    A beta program that scans the PostGreSQL database and prints out
    the contents.

  - pqlib.bet

    A beta library that supports an interface to the PostGreSQL
    database server.

First I downloaded PostGreSQL from
'http://www.se.postgresql.org/sites.html'. Then I installed it on my
linux system. No problems where encountered. Then I initialized the
database by using the command 'initdb' which is part of the PostGreSQL
distribution. Next, I used 'createdb' to create the database which
must be named 'acubase':

(sek@brage.mjolner.dk) bin> ./createdb -e acubase
CREATE DATABASE "acubase"
CREATE DATABASE

Then I started the database server:

sek@brage.mjolner.dk) bin> ./postmaster -i -D /users/sek/postgresql/lib/data
DEBUG:  Data Base System is starting up at Tue Nov 28 14:06:26 2000
DEBUG:  Data Base System was shut down at Tue Nov 28 14:03:39 2000
DEBUG:  Data Base System is in production state at Tue Nov 28 14:06:26 2000

Now it was time to compiled gensympt.bet and executed it:

(sek@brage.mjolner.dk) ~/atle> ./gensympt
PGRES_COMMAND_OK
PGRES_EMPTY_QUERY
PGRES_EMPTY_QUERY

Then I compiled 'listsympt.bet' and executed it,

(sek@brage.mjolner.dk) ~/atle> ./listsympt
----------------------------------------
Contents of database

1, 1001,  Headache
2, 1002,  Pain in lateral
3, 1003,  Headache & pain in back of neck
4, 1004,  Headache involving top of head
.....

Discussion,

Two hours ago I did not know what PostGreSQL was. Still it was
surprisingly easy to find, download and install. The beta interface
you've made for PostGreSQL seems very simple and straight forward. I
did not know it was this easy to save and retrieve data from a
relational database into beta programs.

Other comments,

You write the terminals of the beta language in capital letters.

The indentation of the source files indicate that you did not use the
'mjolner' editing tool for creating the source, why is that?

Alternatively, you can also use emacs which comes with a beta-mode
that will make your programs look really nice, and if you insist on
writing the terminals in capital letters, I'm sure you can have emacs
recognize them for you and capitalize them.

Regards,

Stephan Korsholm
