file connector
file connector. A storage area that contains information about a file; the linkage between a
file name and a physical file and between a file name and its associated record area.
FILE-CONTROL. The name of an Environment Division paragraph that declares the data
files for the program.
file-control entry. An entry in the FILE-CONTROL paragraph in the Input-Output Section of
the Environment Division composed of a SELECT clause followed by one or more
clauses that declare the relevant physical attributes of a file.
file description entry. An entry in the File Section of the Data Division composed of the
level indicator FD followed by a file name and a set of file clauses, as required.
file name. A string of characters that uniquely identifies a file.
In the PC environment, file names for disk files normally have at least two parts (the
disk name and the file name); for example, B:MYFILE.
In the Guardian environment, disk file names include an Expand node name, volume
name, subvolume name, and file identifier; for example,
\NODE.$DISK.SUBVOL.MYFILE.
In the Open System Services (OSS) environment, a file is identified by a pathname; for
example, /usr/john/workfile. See also filename and file-name.
file-name. A user-defined word that names a file described in a file description entry or a
sort-merge file description entry in the File Section of the Data Division.
file organization. The permanent logical structure established for a file when a process
creates it.
file position indicator. A conceptual entity that either:
•
Contains the value of the current key within the key of reference for an indexed file
•
Contains the record number of the current record for a sequential file
•
Contains the relative record number of the current record for a relative file
•
Indicates that no next logical record exists
•
Indicates that the number of significant digits in the relative record number is larger
than the size of the relative key
•
Indicates that an optional input file is not present
•
Indicates that no valid next record has been established
File Utility Program (FUP). The file utility program provided by HP.
filename. In the Open System Services (OSS) environment, a component of a pathname
containing any valid characters other than slash (/) or null. See also file-name and file
name.
