reference page
reference page. The online or hard-copy version of a file that provides reference
information for a software facility. Some UNIX documentation uses the term man page
instead, referring either to the online delivery mechanism used to display the file
(usually the shell man command) or to the nature of the file as part of the manual.
reference parameter. A parameter that is passed by reference (that is, its address is
passed). A called routine can permanently change the value of a reference parameter.
Compare to content parameter.
relation condition. The proposition, for which a process can determine a truth value, that
the value of an arithmetic expression or data item has a specific relationship to the
value of another arithmetic expression or data item.
relative file. A file that has relative organization.
relative key. A data item whose value identifies a logical record in a relative file.
relative organization. A permanent logical file structure in which an integer value greater
than zero uniquely identifies each record, specifying the record’s logical ordinal
position in the file.
relative record number. The ordinal number of a record in a relative file. This number is
handled as a integer numeric literal.
release version update (RVU). A collection of compatible revisions of NonStop operating
system software products, identified by an RVU ID, and shipped and supported as a
unit. An RVU consists of the object modules, supporting files, and documentation for
the product revisions. An RVU also includes a set of documentation for the overall
RVU.
requester. A client that runs only in the Guardian environment by using an interface defined
by HP.
reserved word. A COBOL word
that you cannot use for a user-defined word or a system
name in a source program
.
resource. A facility or service, controlled by the operating system, that an executing
program can use.
RISC. See reduced instruction-set computing (RISC).
RISC instructions. See MIPS RISC instructions.
routine-name. A user-defined word that identifies a procedure written in a language other
than COBOL.
run-time environment. The services provided by run-time library routines and data objects
(data blocks and pointers) to a program at run-time.
