αENTER

This is the vectored ENTER preprocessor. It is act ive when flags –62 and –63 are set. When ENTER is pressed, the command line is placed on the stack as a string and αENTER is executed.

ALRMDAT

ALRMDAT does not reside in a particular directory. You cannot access the variable itself, but you can access its data from any directory using the RCLALARM and STOALARM commands, or through the Alarm Catalog.

ALRMDAT contains a list of these alarm parameters:
