This function determines the ASCII character code corresponding to the first letter in a string.
Asc(string)
Returns an ASCII character code.
Use the function AscB with byte data contained in a string. Instead of returning the character code for the first character, AscB returns the first byte. The function AscW is provided for 32-bit platforms that use Unicode characters. It returns the Unicode (wide) character code, thereby avoiding the conversion from Unicode to ASCII.
