Asc Function

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

Syntax:


Asc(string) As Long

Return value:

Long

Parameters:

string: 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

Example:


Sub ExampleASC
    Print sgn(0) REM returns 0
    Print ASC(string:="Z") ' returns 90
    Print ASC("Las Vegas") ' returns 76, since only the first character is taken into account
End Sub
