Components of an FCOPY Command
You can issue an FCOPY command in several ways, but, whichever method you choose, the
command always has the same components. It identifies a
fromfile ,a tofile , and one or
more functions that you want FCOPY to perform. You enter the FCOPY subsystem from
MPE by typing FCOPY at the MPE colon prompt (:). At the FCOPY prompt (>), you set up
the command. An example of an FCOPY command is:
:FCOPY
>FROM=OLDFILE;TO=NEWFILE;NEW
"FROM" and "TO" Files
A fromfile is the input file for an FCOPY command. It contains the data you want to copy.
A
tofile is the output file to which you want to copy the data.
You identify a
fromfile for an FCOPY command with the FROM parameter. It has the
following format:
>FROM[={
fromfile
* < file >
*
<
empty >}]
The value you assign to FROM can be an input file name (
fromfile ); an asterisk (*) plus a
file name, if desired; an asterisk (*); or nothing at all (<
empty >). An asterisk preceding the
fromfile backreferences the fromfile named in a previously set file equation. An
asterisk, alone, specifies continued use of the
fromfile specified in the previous command.
If you leave FROM empty, you can use your terminal (or a spoolfile during a job) as the input
file.
In the example below, the FROM parameter describes an input file named INFO1 for an
FCOPY command.
>FROM=INFO1
