In addition to some improved error-checking in the complier, the latest version of Ozapell Basic introduces KEYBOARDSINGLEON and KEYBOARDSINGLEOFF.
Normally, a user can hold down a key and it will repeat endlessly after a short delay.
KEYBOARDSINGLEON stops repeating keypresses and requires users to press a key and then release it. This could be useful for strategy or puzzle games where repeating keypresses are unnecessary.
KEYBOARDSINGLEOFF returns to the previous handling of repeating keypresses.
Have fun!
