:Repeat getKeyʳ=64:End
Although the new getKeyʳ is more useful, it can also now be very confusing. For example:Code: [Select]:Repeat getKeyʳ=64:EndCould cause an infinite loop that may be impossible to get out of, if lowercase is enabled.The reason for this is that if you type a lowercase letter, it is stored at $8446, but if you type any other key, it does not reset the value at $8446. (Edit: This causes all of the other keycodes to change to different values every time a lowercase letter is typed.) On the plus side, its value does seem to always be reset at the beginning of the program.Some fixes for this are to only read $8446 if a >= $fc, reset $8446 after it is read, or to change checks for any key that is not a lowercase letter to getKeyʳ^256=key code.Edit: And in the last case, it should probably be documented somewhere, since it is not obvious just from playing around with getKeyʳ.

This also means error scrolling can finally be automatic since it won't ever crash. No need to press [prgm] anymore, it will always take you to the error unless you press [clear].
