RMS message variable. An RMS variable that contains information on a message that
arrives at a message handler.

timer performs tasks at specific times under the control of a user as specified by the
rule.
ROC. See Remote Operator Control.
roll-delete message. A message that “rolls off” the message display area of an OCS
window. Roll-delete messages report events that are not critical.
roll-delete message area. The area on an OCS window that displays roll-delete messages.
roll-delete message area delimiter line. The line on an OCS window that separates old
roll-delete messages from new roll-delete messages.
roll-delete message queue. A queue that holds roll-delete messages. Each OCS window

rule. A member of an RMS ruleset that contains information on what to do when an
event occurs.
rule action. A user-defined action in an RMS rule that executes when an event triggers
the rule.
rule action exit NCL procedure. An optional user exit NCL procedure that executes before
the other RMS rule actions when the rule containing the exit is triggered. The
procedure executes inline with the message handler for a message action rule but
separately from the message handler for a message group rule.
rule contents variable. An RMS variable that contains the value of certain rule definition
elements. The variable name has the prefix $RMS.
ruleset. A collection of RMS rules that defines responses to events such as message
arrival and time conditions. The message handler uses the information in a ruleset to
set up its execution environment and respond to incoming messages. The timer driver
uses the information in a ruleset to set up the execution environments for the timers
that respond to time events.
