How to check a DEL button is pressed
 

Hello,

I am using AmiBlitz3. My code is like this retVAL$=Inkey$(1) where the key value is returned to variable retVAL$.

How do I take this variable retVAL$ and use it to compare if a person pressed the ESC key? Thanks in advance.

You can look at the ASCII code of retVAL$ using Asc(retVAL$). This will give you the ASCII character code for non-printable characters such as escape, arrow keys, backspace and so on.

ESC = 27
