Explanation

|
EXPIRED AFTER <timestamp>
|
Copies files whose last access date plus the minimum
of the SAVEFACTOR and the SAVECONSTANT values of each file is less
than or equal to the timestamp. The default value for SAVECONSTANT
is 60.
If you do not specify a value for the AFTER timestamp,
FILECOPY extracts the TODAY value from the system, and performs checking
based on the AFTER option.
|
|
EXPIRED SAVECONSTANT <integer>
|
Overrides the SAVEFACTOR value of each
file if the value of SAVECONSTANT is less than the value of SAVEFACTOR.
The algorithm used for EXPIRED is as follows:
LASTACCESSDATE + MIN(SAVEFACTOR,SAVECONSTANT) LEQ AFTER
date
In this algorithm, LASTACCESSDATE
is the date the file was last accessed.
Normally, FILECOPY uses the SAVECONSTANT value to determine
the EXPIRED condition for all files that have a SAVEFACTOR value of
zero (0). The SFACTORZERO option causes FILECOPY to use the zero SAVEFACTOR
of a file to determine whether the file is expired. Refer to “FILECOPY
Options” later in this section for more information.
The default value of SAVECONSTANT is 60.
You can alter the default by recompiling FILECOPY after you change
the define DEFAULTSFOVERIDE in SYMBOL/FILECOPY. The SAVECONSTANT option
enables the system to define when a file has expired instead of permitting
each file to define its expiration date.

|
<filecopy modifier>
|
Provides the following:
-
The names and kinds of disks
from which files are to be copied
-
The names of the files and directions from which FILECOPY
should select files for copying
-
The name and kind of the output
disk, tape, or CD-ROM
-
Other control information
