JAWS
by Mark Hubbuck
from Sinclair User 24 (March 1984)

You are swimming in the sea in search of treasure. Watch for the man-
eating shark and the crabs which appear at random. As the game
progresses the sea bed rises, giving you less room to manoeuvre, and it
becomes more difficult to escape the shark and avoid the crabs. Jaws was
written for the 48K Spectrum by Mark Hubbuck of Newport, Shropshire.

HAUNTED HOUSE
by Babar Abidi (not)
from Sinclair User 24 (March 1984)

[The actual author of this program was Andrew Murgatroyd]
[- see letter below.                                JimG]

Collect the jars from under the chimney and take them back to your van.
Lay snares to trap the pursuing ghosts and pick up the hammer which you
can use to eliminate the skeleton. Haunted House was written for the 16K
Spectrum by Babar Abidi, aged 13, of London SW19.

Cracking down on copying

Haunted House, published in March Sinclair User, had a line omitted. It
should read "6 RETURN". In the same program, for any readers wondering
what significance the skeleton, ladder and ghost graphics characters
beside the score have, they should not be there at all.

The letters AJM are the initials of the original author, Andrew
Murgatroyd, from the August 1983 Computer and Video Games, where the
program was originally published.

The two programs are identical except for the removal of several AJM
lines. I understand that not every entry can be checked for originality
but I feel that such an obvious copy as this should have been discovered
before printing.

Paul Bamborough,
Newcastle-upon-Tyne.

It has been brought to our attention by a number of readers that Haunted
House was not the original work of the person who submitted the program.
Our investigations have confirmed that.

While we make every effort to ensure that all programs published in
Sinclair User have not been published elsewhere, occasionally one may
slip through the net. Fortunately our readers are quick to inform us of
any obvious plagiarism.

We take this opportunity to warn readers that programs which have
appeared elsewhere, in book, magazine or cassette form, cannot be
considered for inclusion in Sinclair User, whether or not such programs
are the contributor's original work.
