Vector Table



Vector Table is one of those seemingly pointless routines

which so many of us find so fascinating. Once entered and

run a machine code routine is set up at 64250+.

   To start it type RANDOMIZE USR 64319 and to cancel it

type RANDOMIZE USR 64337. Make sure that no code is placed

above 62000 or else the machine will crash.

   So what does it do?

   Well, after starting it you will find that pressing keys

0 and 9 at the same time will clear the screen and leave it

blank - to bring back the display press key q.

   Perhaps useful for those who suffer from obsessive

secrecy and who do not want other to see what they are

doing on the computer? Useful for BBC programme producers?

   Our thanks to Hugh Shaw of Ayrshire for this one.
