Channel 2, including all invisible data
values
on the left-hand

of the
screen. The address -32000 is
usually
out
of range,
but
the
9400A
automatically
adapts
to the
closest
legal value. This complete data record
is restored in memory C with the command
WRITE MC.*,~,-32000.

The 9400A checks
the

When transferring WRITE DATA without specifying the number of data
values, the nominal number + I data values must be sent to the 9400A
(25000 + 1 data values for example). This additional value may
needed for the generation of the last displayed point at the right
hand side of the screen.
