To create this pattern,
use
the
CURSOR
1key
as
KeY1
and the asterisk
(*)
key
as
KeY2'
As vou hold down
KeY1'
repeatedly press and release
KeY2;
the cursor
will
automatically move and print the
"*"
in
a diagonal line. Following
is
a
flowchart of the process:
Press
KeY1
CURSOR!.
Do

Press Keyz

As vou can
see.
if vou hold down
KeY1
as

KeY2.

two
keys were being pressed alternately.
etc.
But if
KeY1
is
released while
KeY2
is
depressed.
KeY1
will
not
be
printed a second
time.
There
are
countless combinations available for repeating sequences
on
the
PET.
Since three-or-more-key repeating sequences have limited
use
and varied
and unpredictable results. they
will
not
be
covered
in
this book, but may serve
as
an
interesting exercise for the curious programmer.
