Correcting INPUT

[bitvast]

When you input a number from the terminal you cannot correct it because using the BACKSPACE key generates control characters. Is this a limitation of BaCon or can it be fixed?

Hey bitvast


You can correct with backspace with this type of input in bacon

'--- input-test.bac
INPUT "Type a string   ",a$
PRINT "You entered the following: ", a$


INPUT "Type a number  ",b
PRINT "You entered the following number: ", b


or if you give an example of the problem we can test
to see if we get the same results or not

It may be a problem reading your keyboard's backspace key
Try ctrl+backspace and see if that works or not


If the code snippet still doesn't work for you (use "locate bashrc" depending on the linux you are using)

And backspace doesn't work properly try putting this your bashrc

stty erase ^?

Hi Joe,

Ctrl + BACKSPACE works, thanks. Alternatively I suppose you could use strings and then convert with VAL() before using them in calculations.

because using the BACKSPACE key generates control characters.

For me, BACKSPACE works as it should (no control characters), this is on Linux Mint.

Not sure what causes your issue, maybe the kind of terminal you are using, for example xterm? With MATE terminal it works as it should.

Hi Peter,

I was using the default terminal in Bacongui, which is xterm (xterm -hold -sb -geometry 90x30 -e @), but changing to xfce4-terminal has fixed the problem. Cheers.
