object program
object program. A set or group of executable machine language instructions and other
material designed to interact with data to provide problem solutions; the machine
language result of the operation of a COBOL compiler on a source program.
open mode. The state of a file after a process executes an OPEN statement for the file and
before the process executes a CLOSE statement (without the REEL or UNIT phrase)
for the file, governing the types of operations a process can perform on the file; one of
these modes, which you can specify in an OPEN statement:
•
INPUT mode
•
OUTPUT mode
•
I-O mode
•
EXTEND mode
OSS ASCII text file. See line sequential file.
Open System Services (OSS). An open system environment available for interactive or
programmatic use with the NonStop operating system. Processes that run in the OSS
environment use the OSS application program interface; interactive users of the OSS
environment use the OSS shell for their command interpreter. Compare to Guardian.
operand. In syntax formats, any lowercase word or words that appear in a statement or
entry format; an implied reference to data or to a literal value.
operational sign. An algebraic sign associated with a numeric data item or a numeric literal
to indicate whether its value is positive or negative.
optional file. An input file that you declare is not necessarily present during each execution
of the object program, the presence or absence of which file the object program
determines during execution.
optional word. A reserved word
that appears in a syntax diagram of a statement or entry
only to improve readability and that you can omit when you use the statement or entry
in a source program
.
OSS environment. The application program interface (API), tools, and utilities of the Open
System Services (OSS).
OUT file. The output file of a process, either specified explicitly at process start time or
inherited from the parent process.
output file. A file open in either the output mode or the extend mode.
OUTPUT mode. The state of a file after a process executes an OPEN statement that
includes an OUTPUT phrase for that file and before the process executes a CLOSE
statement (without a REEL or UNIT phrase for that file); EXTEND mode includes the
capabilities of OUTPUT mode.
