83Plus:RAM:8446
From WikiTI
Synopsis
Official Names: keyExtend, EXTECHO
Memory Address: 8446h
Length: 1 byte
This byte stores the second byte of a two-byte keycode.
Comments
A two-byte keycode is usually represented by A containing one of these three values:
- kExtendEcho (0FEh)
- kExtendEcho2 (0FCh)
- kExtendEcho3 (0FDh)
The second byte is then placed here. For example, the keycode for a lowercase 'a' is kExtendEcho2 + 0E2h. So GetKey would return A = 0FCh, but would set (keyExtend) to 0E2h.
