Asc Function

Office VBScript

Microsoft® Visual Basic® Scripting Edition Asc Function

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.
