[ROM Call]
Index=$481

[Description]
Turns the alpha-lock on on the TI-89.

[Explanation]
alphaLockOn first returns the current alpha-lock keyboard status in <I>Status</I>. Then it turns the alpha-lock on.
This routine exists on both the TI-89 and TI-92+, but as there is no alpha-lock on the TI-92+, this function does nothing on the TI-92+.
