VBS TUTORIAL: function-ASC function _vbs

ASC function

Returns the ANSI character code corresponding to the first letter of the string.

Asc(string)

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

Description

In the following example, Asc returns the ANSI character code for the first letter of each string:

Asc("A") 'Return  65 . Asc("a") 'return  97 . Asc("Apple") 'return  65 .

Note that the AscB function is used in conjunction with a string containing byte data. Instead of returning the character code for the first character, AscB returns the first byte. The AscW is provided for 32-bit platforms that use Unicode characters. It returns the Unicode (wide) character code, so you can avoid code conversions from ANSI to Unicode.
