Alt-Code Documentation is Currently Incorrect.

07 Dec 2023, 18:26

On the current documentation for the Send functions, in both v1 and v2, the pages state the following for "{ASC nnnnn}":
To generate ASCII characters, specify a number between 1 and 255. To generate ANSI characters (standard in most languages), specify a number between 128 and 255, but precede it with a leading zero, e.g. {Asc 0133}.

However, alt-codes without a prefixed zero between 1 and 255 do not send ASCII characters, they send code page 437 characters, also known as extended ASCII. The two character sets coincide for the printable ASCII characters and the Null character, but for the unprintable ranges and for the characters above 127, code page 437 defines different printable characters than ASCII does. For example, in ASCII 1 is defined as the SOH (start of heading) character, but in code page 437, it is ☺, the smiley character. This could confuse users who actually want to send the ASCII control characters.

Thanks for reporting. I've changed "ASCII characters" to "printable ASCII characters or other characters from code page 437".
