void alphaLockOn (unsigned char *Status);

Turns the alpha-lock on on the TI-89.

alphaLockOn first returns the current alpha-lock keyboard status in Status. 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+.

Used by: Dialog, MenuKey, ROM Call 0x421
