test mode. A mode that forces NonStop NET/MASTER MS to load an NCL procedure
from disk and compile it before executing it, rather than attempting to find a compiled
version.
text. A string of characters that does not modify the action taken by a NonStop
NET/MASTER MS command.
text or a number. An NCL expression following a verb keyword that NCL regards as
text or a number. The expression terminates at the next keyword or at the end of the
statement.
TH. See transmission header.
thaw. The act of reactivating RMS rules for a subject. You thaw a frozen subject.
time prefix. The identifier that can precede an unsolicited message displayed on an OCS
window. It indicates the time the message was generated.
time-based rule. An RMS rule that invokes a timer to perform tasks at specific times
under the control of a specified user.
timer command. The AT or EVERY command, used to execute a NonStop
NET/MASTER MS command at a certain time or a certain frequency.
timer driver. An NCL procedure that loads RMS time-based rules as timers.
timer ID. An identifier assigned to a timer command by a user.
timer queue. The queue holding AT and EVERY commands pending execution.
tokenization. The process of splitting a message into parts. Also, in NCL, the process of
converting lexical elements to machine language.
top level. The highest level in a hierarchy of nested blocks: for example, the procedure
that encloses all other procedures and functions.
top-level environment. The environment in which the NCL processes that display
NonStop NET/MASTER MS menus operate.
TPL. See trace parameter list.
trace collector process. The NonStop NET/MASTER MS process that controls a running
trace and the writing of records to a trace file.
trace file. A file that collects and stores trace records.
trace ID. The unique number that NonStop NET/MASTER MS assigns to a trace when
the trace is started.
trace parameter. A value in the trace parameter list specifying the events to trace.
trace parameter list (TPL). A list associated with an OCS window that holds the current
trace parameter settings.
trace point. A NonStop NET/MASTER MS code position that can be traced.
trace record. An entry in a trace file: a message mapped by the map $MSG, text data, or
