Syntax:
var = StringToByte(string) 'Supports decimal byte range strings only.Command Availability:
Available on all microcontrollers
Explanation:
The StringToByte function will extract a number from a string variable, and store it in a byte variable. One potential use is reading numbers
that are sent in ASCII format over a serial connection.
The StringToByte function will not extract a StringToByte from a hexadecimal string.
