Flags
The modes that you are more likely to want to change can be changed
easily using the input forms described in the last three sections. There are,
however, many more modes that you can change.
Tírese additional modes can be changed by setting or clearing certain
flags. For example, by setting flag -60, you can lock the alpha keyboard by
pressing
(5M)
once, ratlrer than twice. Clearing flag -60 returns the mode
to its default setting (where (ALPHA) must be pressed twice to lock the alpha
keyboard).
