Description
Returns the ANSI character code corresponding to the first letter in a string.
Syntax
Asc(string)

The string argument is any valid string expression. If the string contains no characters, a run-time error occurs.

Remarks
In the following example, Asc returns the ANSI character code of the first letter of each string:
Dim MyNumber
MyNumber = Asc("A")      'Returns 65
MyNumber = Asc("a")      'Returns 97
MyNumber = Asc("Apple")  'Returns 65

Note  The AscB function is used with byte data contained in a string. Instead of returning the character code for the first character, AscB returns the first byte. 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 ANSI.
