The electrical interference effect is now official [slow ain't they]
On modern computer chips the connections/routing is very close
together and electrons can 'drift' across and the human magnetic field is
strong enough to influence this.
Possibly sometimes a stronger field is being generated . . .

It can work the other way round . . .
for example St Paul on the Rd to St Damascus
was blinded by (this is the scientific theory
- when earth moves together - he was in a known
earthquake area - great electrical charges can be produced.
This includes ball lightening and it is this that he may have
been hit by and blinded by . . .)

The American military have the ability to create
a charged fire ball (forget exactly how) which they
can cause to produce sound.
The were going to use this as the 'voice of Allah'
telling soldiers to surrender
in a black ops effort
in the first Saddam war but decided it would
create bad press back home . . .

"BBCBASIC, with its definable functions and re-entrant procedures, is structured."

"BBC BASIC -- designed for Acorn's BBC micro
-- added control structures and procedures, and is a greatly improved language, but is still suitable only for small programs.
It extended traditional BASIC with procedures and functions, REPEAT...UNTIL loops, and IF...THEN...ELSE structures. "

- could not find a direct Modula 2 ref

Was BBC Basic based on Modula 2?
Well I read that (probably in Acorn User)

It used functions and Procedures and structure and
could house assembler and was faster than the
compiled C program I had in one short program
(the one and only C program wot I ever dide)

Are we returning to optimised interprters?

meanwhile I will be using this
