VAL
The
VAL
function
changes the numbers in a character variable
into
a numerical value.
Format: VAL (character variable)
Since this
function
changes the numbers in the character variable
into
a numerical value,
when there
are
no numbers in the character variable (for example,
"ABC"),
an
error
will
occur.
Example:
If
Z$=
"78963",
VAL
(Z$)
=78963
Note: When this
function
is
used
in a program and
an
error occurs
as
a result
of
lacking
numbers in the data,
'IE
RR
2"
will
be
displayed
but
not
the program
area
and
line number.
