I-O mode
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).
language-specific run-time library. A collection of routines outside the CRE that supports
requests from a specific language for services such as I-O and heap management,
math and string functions, exception handling, and error reporting.
ld utility. A utility that collects, links, and modifies code and data blocks from one or more
position-independent code (PIC) object files to produce a target TNS/R native object
file. See also eld utility and nld utility.
letter. A character belonging to one of these two sets:
level indicator. Two alphabetic characters that identify a specific type of entry in the Data
Division: file description entry or sort-merge file description entry.
level-number. A user-defined word that indicates the position of a data item in the
hierarchical structure of a logical record (a number in the range 1 through 49); a user-
defined word that indicates the special properties of a data description entry (the
numbers 66, 77, and 88).
