paint program, need help

[Agamemnus]

EDIT..
ok, your code is complete rubbish now...

Example of how to fix. Your code.

Code:

DO
4
i$ = inkey$
IF i$ = "s" OR i$ = "S" THEN LOCATE 6, 1: INPUT "Are you sure you would like to SAVE? Y/N", response$
'IF response$ = "y" OR response$ = "Y" THEN BSAVE
IF response$ = "n" OR response$ = "N" THEN RETURN
IF response$ <> "y" OR response$ <> "Y" or response$ <> "n" OR response$ <> "N" then goto 4
LOOP until i$ = ""

The code you should be using.

Code:

DO
IF i$ = "s" OR i$ = "S" THEN LOCATE 6, 1: INPUT "Are you sure you would like to SAVE? Y/N", response$
response$ = UCASE$(response$)
'IF response$ = "Y" then BSAVE

I$ = INKEY$ assigns the key pressed value to I$ at that moment in time.

Code:

INPUT "statement"; variable1$

...does a keyboard prompt, and the result is stored at the end.. variable1$ in this case.
