func-
tion

Character string:
Explanation:
1)
If
placed
at
the
beginning
of
a
hexadecimal,
it
will
be
converted
to
a
decimal
integer
value.
Although
&H
is
shown
as
a
function
since
it
functions
opposite
to
HEX$,
strictly
speaking,
it
is
not
a
function
but
is
actually
a
hexadecimal
. identifier.
2)
Since
the
conversion
result
will
be
a
decimal
integer
with
the
range
of
-32768
to
+32767,
&HFFFF,
for
example,
will
not
indicate
65535
but
-1.
3)
The
0
placed
at
the
top
of
a
hexadecimal
and
spaces
in
a
hexadecimal
charac-
ter
string
are
disregarded.
<Example>
&HO010 indicates 16 of a decimal number.
&HAwW B indicates 171 of a decimal number.
&HUA indicates 10 of a decimal number.
(J means a space.)
4) An error (Error 2) will occur if a hexadecimal character string exceeds four
digits or if there is a character other than a hexadecimal in the character
string.
<Example>
&H 10000 -> Error 2 (Five digits)
&HAG Error 2 (Gis not a hexadecimal)
&HA# Error 2 (#is not a hexadecimal)
