VAL
Field of Application Function returning the numeric representation of a string expression.
Syntax VAL(<sexp>)
<sexp> is the string expression from which the numeric representation
will be returned.
Remarks
VAL is the complementary function for STR$.
VAL ignores space characters from the argument string to determine
the result.
If the fi rst character in the string expression is anything else but a digit, a plus
sign, or a minus sign, the VAL function returns the value 0.
Example In this example, the values of the string variables A$ and B$ are read and
assigned to the numeric variables A% and B%:
10 A$="123, MAIN STREET"
20 A%=VAL(A$)
30 B$="PHONE 123456"
40 B%=VAL(B$)
50 PRINT A$
60 PRINT A%
70 PRINT B$
80 PRINT B%
RUN
yields:
123, MAIN STREET
123
PHONE 123456
