Asc Function

Description

Returns an Integer representing the character code corresponding to the first letter in a string.

Syntax

Asc(string)

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

Remarks

The range for returns 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 except on platforms where Unicode is not supported, in which case, the behavior is identical to the Asc function.

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.
