VbsEdit is a VBScript and Javascript editor


Asc(string)

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

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

	Copy Code
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.
