Val

Name

Val -- convert a string to a number

Synopsis

var, chrs = Val(string$)

Function

Converts the specified string into a number. If the string does not start with a number, 0 will be returned. The string can also contain hexadecimal numbers starting with a "$".

Starting with Hollywood 2.0 you can also pass a string which contains a binary number to this function now. Simply prefix it with a '%' character. Additionally, a second value is returned now which specifies how many characters Val() has read from the string. This allows you to determine the length of the number.

Inputs

string$: string to convert to number

Results

var: variable that receives the converted number
chrs: number of characters converted

Example

result, chrs = Val("500 people were on the train.")
Print(result, "-", chrs)

This will print "500-3" to the screen.
