Asc, AscB, AscW
Returns an Integer representing the character code corresponding to the first letter in a string.
Syntax:
- Asc( string )
- AscB( string )
- AscW( string )
- string
- required Any valid string expression. If string contains no characters, a run-time error occurs.
The range for returns from Asc is 0–255 on non-DBCS systems, but -32768–32767 on DBCS systems.
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. The AscW function returns the Unicode character code.
The functions Chr, ChrB, and ChrW are the opposite of Asc, AscB, and AscW. The Chr functions convert an integer to a character string.
Example
This example uses the Asc function to return a character code corresponding to the first letter in the string.
Dim MyNumber
MyNumber = Asc("A") ' Returns 65.
MyNumber = Asc("a") ' Returns 97.
MyNumber = Asc("Apple") ' Returns 65.
