This directory contains demonstration programs:

===========================================================
1: 20 spm GAJ  ALGOL.flx
2: 20spm.flx
3: TYVES (tyves)  rhak.flx
4: 20spmin.flx
5: tyves Kopi 75.02.10 GA4 rhak.flx

Different copies of the "20 questions" game.
You'll have to think of a country, and GIER
will guess it in 20 question.

Note, this game is old; geography has changed
since then.

Tape 1 is in GIER ALGOL III
Tape 2 is in GIER ALGOL 4
Tape 3 is binary
Tape 4 contains input data read by the program. When
the program finishes, a new tape with statistics is
produced on the punch. Use this tape for the next run.
Tape 5 is in GIER ALGOL 4. Read the tape by "r<",
and it will install itself so that it can be
started by "run,tyves<". I've modified the program
so that the statistics are stored on the disc.

===========================================================
Euklids algoritme.flx

SLIP program. I don't know how it works.
===========================================================
Fred + Winnie GA4 algol rhak.flx

Read by "r<". Direct output on 64 to the line
printer, using the aux. control board. Prints
out pictures of Winston Churchill and Fred Flintstone.
===========================================================
GIER orgel.flx

Primitive "organ". Read by "r,slip<". Use the typewriter
as the keyboard
===========================================================
Glædelig jul  HJÆLP.flx

Plays a Christmas song. Load the "HJÆLP" system, and read
this tape by "_l".
===========================================================
MUSIK.flx

The tape contains a series of music program. Each is
read in by "r<".
===========================================================
Madonna ga4.flx

Direct unit 64 to the line printer before starting this
program by "r<". Prints the same picture on the line printer
over and over again.
===========================================================
Pindespil - rhak 30.07.72.flx

I don't know what this does.
===========================================================
SORTEPER.flx

I don't know how this works.
===========================================================
bach.flx

Read by "r<". Plays BWV 147.

10: demon7.flx

These are all demonstration programs written by my father,
Jørgen Kjær, working for Haldor Topsøe.

Tapes 1-4 are old versions of later demonstration programs.
Those I found on tapes that have been distributed to
other GIER installations.

Tapes 5-11 are programs I've typed in from my fathers
documentation of these programs.

Tape 1: Originally written in GIER ALGOL II, but a wrapper
block is included so that it will run under GIER ALGOL III.
This is the Danish version.

Tape 2: English version

Tape 3: Binary?

Tape 4: Demon 1E. English version. I've translated this
so that it will run under GIER ALGOL 4.

Tape 5:	Demon 3: The game of Nim. I've translated this into
GIER ALGOL 4.

Tape 6: Original GIER ALGOL III version of Demon 3.

Tape 7: Demon 5. Calculation with large numbers.

Tape 8: Input tape, required by Demon 5. The program
starts by reading a set of commands from paper tape,
demonstrating the command system used by the program.

Tape 9: Alternate input tape for Demon 5. Calculates
exp(pi*sqrt(n)) where n is an integer from 1 to 163.

Tape 10: Demon 7. Calculation of prime numbers.

I don't know how this tape work.
