NRD message with the OPER attribute. A NRD message that is not held in the NRD
message central queue, and must be deleted using NRD cursor deletion. When
deleted, the message immediately disappears from the NRD message display area.
null. No value. In NCL, assigning a variable a null value does not delete the variable
name from memory.
number. In NCL, a number is a symbol that begins with a digit (0 through 9) or a
period and is in a context that permits it to be a number (rather than a string).
object. In NCL, the object code of a specific NCL procedure that is loaded into
memory. In SPI, an entity subject to independent reference and control by a
subsystem: for example, a disk file or a data communications line. An object typically
has a name and a type known to the controlling subsystem.
object code. NCL code in executable form.
object file. A key-sequenced file containing the object code of all NCL procedures
owned by a certain user.
object procedure library. A subvolume in which NCL object files are kept.
OCS. See Operator Control Services.
OCS ID. See OCS window ID.
OCS mode. The presentation mode in OCS where a window allows a real user to enter
NonStop NET/MASTER MS commands at any time and allows NonStop
NET/MASTER MS to display output at any time. In OCS mode, there is no
correlation between input and output.
OCS profile. A profile that determines what a real user can do in OCS; the user can
change certain aspects of this profile by using the PROFILE command.
OCS window. The screen display in OCS.
OCS window ID. An identifier displayed in the bottom right corner of an OCS window
that helps to identify the window when using more than one.
offset. The position of a character in a group of characters relative to the beginning of
the group. The first character in a group is deemed to start at either offset 0 or offset 1.
ON block. The condition handler, established by the ON core statement, raised by a
certain block of statements.
opcodes. Statements representing the object code created by compiling NCL source
code.
open code level. The top level of code in an NCL procedure; the block of statements
bounded by the core statements PROCEDURE and END or FUNCTION and END that
encloses all other blocks in an NCL procedure.
operand. Following a NonStop NET/MASTER MS command, a word that modifies the
action taken by the command. There are three types of operands: text, qualifiers, and
positional arguments. In NCL, a word that modifies the action taken by a verb. All
operands are in the form: keyword[ [ = ]value ].
