HOW I BACKSPACE

Is there an escape seecwhence for backspacing instead of:
a$=right$(a$,len(a$)-1)

IN B4 LISP FAGS

Are you writing to stdout? If so, I'm pretty sure there is, but fuck if I remember. Ask on /prog/

\b

Lulz.

I don't know what right(,) does. Enlighten me.

\x08 or \b

Here's how you get a backspace in a program:

cout << "Please press the backspace key now." << endl;

>>7

isnt it like... \b?

>>4,6,8
Appears as a non-printable character in console

>>9
Whatever console you are using doesn't seem to support ASCII, then.

\x08 or \b in most programming languages usually refers to the ASCII BACKSPACE (BS) character.

cmd.exe supports it, so whatever you're using must be fucking awful.

When I echo -e "abc\b" I get abc. When I echo -e "abc\bd" I get abd. Perhaps it's something like that.

in lisp (backspafe)

Surely you mean (format t "backspathe").

>>11
echo -e "abc\b "
(note the space)
yields the desired result. I guess you have to have at least one character after the backspace

>>15
\b moves the current cursor position back one character, it doesn't actually modify the screen buffer (it's behavior is akin to the backspace you'd find on a typewriter). If you want to erase the character that was there, you have to first overwrite it with something else (ie, a space).

I meant, ask on reddit.
