Asc Function

Returns the ASCII (American Standard Code for Information Interchange) value of the first character in a string expression.


Asc (Text As String)

Return value:



Text: Any valid string expression. Only the first character in the string is relevant.

Use the Asc function to replace keys with values. If the Asc function encounters a blank string, LibreOffice Basic reports a run-time error. In addition to 7 bit ASCII characters (Codes 0-127), the ASCII function can also detect non-printable key codes in ASCII code. This function can also handle 16 bit unicode characters.

Error codes:

5 Invalid procedure call


Sub ExampleASC
    Print ASC("A") REM returns 65
    Print ASC("Z") REM returns 90
    Print ASC("Las Vegas") REM returns 76, since only the first character is taken into account
End Sub
