VAL (Function) [Conforms to SLIM]

Function

Converts a character string to a numeric value.

Format

VAL (<Character string >)

Explanation

This statement converts a character string designated in <Character string > to

a numeric value.

If the first character of <character string > is not +, -, &, or numeric value, VAL

becomes 0.

Explanation: If the system finds a character other than the figures in the

character string, the Val Function stops reading. The Val

function does not interpret symbols or letters which are

normally regarded as part of a numeric value such as the

yen symbol (\) or comma (,). However, the Val function

does recognizes prefixes &H (hexadecimal number) and

&B (binary number). Blanks, tabs and line feeds in the

character string of an argument are ignored.
