VBScript Asc Function

Returns the ANSI character code corresponding to the first letter in a string.

Syntax: VBScript Asc Function

Asc(string)

Arguments: VBScript Asc Function

string

Any valid string expression. If the string contains no characters, a run-time error occurs.

Remarks: VBScript Asc Function

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.

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.
