Backspace handling

[Mike Keys]

Well, thanks to this forum, I'm almost done writing the script I have been working on. Just applying some finishing touches to it.

One thing I need to do is a little input handling. How would I go about coding the input from STDIN to accept a backspace (i.e. if a user types in a wrong letter, they can press backspace to delete the mispelled letter).

Also, in conjunction with this, I need to fix the input cursor and not allow the user to backspace/delete past the first character.

O.K. how about this. The delete key works as I want it to. Can I disable to function of the backspace key when running a perl script?

Problem was with terminal definition.

Try following.

tput 25,25
echo "Key in the CHOICE"
stty erase "the_back_space"
# (You do that with stty erase ^backspace key)

your stuff goes here.

This should work without problems.

stty erase (hit spacebar once) (hit returnkey)
It works.

Also, Ctrl+hkey works to backspace.
