internal data
internal data. The data described in a program, including all internal data items and internal
file connectors. Items described in the Linkage Section of a program are handled as
internal data.
internal data item. A data item that is described in one program in a run unit. An internal
data item can have a global name.
internal file connector. A file connector that is accessible to only one object program in the
run unit.
invalid key condition. A condition caused at object time when the process determines that
a specific value of the key associated with a structured file is invalid—has a value to
which no record in the associated file corresponds, or has a value which exceeds the
bounds of the file, or specifies a value that would cause a duplicate key value in the file
where no duplicate key values are allowed.
I-O-CONTROL. The name of an Environment Division paragraph that specifies object
program requirements for specific input-output techniques, rerun points, several data
files sharing the same areas, and multiple file storage on a single input-output device.
I-O mode. The state of a file after a process executes an OPEN statement including an I-O
phrase for the file and before the process executes a CLOSE statement (without the
REEL or UNIT phrase for the file), allowing the process to read records from the file
and write records to the file.
I-O status. A conceptual entity that contains the two-character value indicating the resulting
status of an input-output operation. This value is made available to the program
through the use of the FILE STATUS clause in the file-control entry for the file.
job. The output from a process that a spooler receives and stores on a disk, queued for
delivery to a print process.
key. A data item that identifies either:
•
The location of a record
•
A set of data items whose values a process can use to order data
key of reference. The prime record key or alternate record key that a process is currently
using to access records in a structured file.
keyword. A character sequence recognized by a command process.
language-specific run-time environment. A set of services implemented by the run-time
library of each language; a non-CRE environment. Without the CRE, HP C,
HP COBOL, FORTRAN, Pascal, and pTAL programs each have their own
language-specific run-time environments. These language-specific run-time
environments are often incompatible with each other. Compare to Common Run-Time
Environment (CRE).
