ENTERLEVEL 2.0 nn subprogram level number
EXCP 2.0 nn last Comet exception
HELPKEY$ 4 user-defined user-defined value for Comet Help System
ITERM$ 3 "Tnn" or "nnn" initiating terminal number
LONGYEAR 4.0 YYYY current year in long format
LONGYEAR$ 4 "YYYY" current year in long format
MESSAGE$ 32 user-defined user-defined string for passing messages to overlays
PARTITION$ 3 "Pnn" or "nnn" current partition number
PRIORITY$ 1 hex partition scheduling priority
RUNSTATE 1.0 n security value for current partition
