COPY
Copies one file to another by creating a new file or by overwriting an
existing file.
The COPY command can be used to copy files to and from HFS directories.
You cannot use COPY to copy directories to or from other directories.
Users with SM capabilities are able to copy files to MPE accounts outside
of their current logon account.
Syntax
[ASK]
COPY [FROM=]sourcefile[{;TO=}targetfile][YES]
[{, } ][NO ]
Parameters
sourcefile The name of the file that is to be copied.
A file with HFS syntax must begin with a dot (.),
or a slash (/).
targetfile The name of the file to which sourcefile is to be
copied. If targetfile is omitted, the source file
is copied to sourcefile in the user's current
working directory (CWD). You may qualify targetfile
with both file and group name, or specify only the
destination group. If only group is specified,
COPY puts a copy of the source file in a file
called sourcefile in the specified group.
Since .groupname can be specified as the
targetfile, and HFS file names can also start with
a dot (.), this could lead to confusion as to
whether an MPE group or HFS file name is desired
for the targetfile. If the targetfile is an HFS
filename starting with a dot (.), then the
targetfile must be preceded with a dot and slash
(./). For example, to represent a targetfile .FOO
in an HFS current working directory, the file must
be represented as ./.FOO.
The max extent value for targetfilet value may not
be the same as for sourcefile.
ASK If targetfile already exists, COPY prompts the user
to choose an action with the following prompt:
PURGE OLD targetfile?
Valid replies to this prompt are:
Y or YES Instructs COPY to purge the
original targetfile and
create a new targetfile.
N or NO Instructs COPY to terminate.
ASK is the default, except in a job or in other
cases when the user is not using interactive mode.
In such cases, ASK has no meaning, and YES becomes
the default.
YES Instructs COPY to purge targetfile if it already
exists. No message is displayed for the user, as
would be the case with ASK. YES is the default in
jobs, or at other times when the user is not using
an interactive mode.
NO Instructs COPY to terminate if targetfile already
exists.
You may not specify system-wide ($ prefix), CM
KSAM, or privileged files as sourcefile or
targetfile.
Operation Notes
This command performs a fast copy of sourcefile to targetfile and leaves
sourcefile unchanged. Both files must be nonspooled disk files residing
on the host system. You may specify files that are backreferenced with a
file equation (*). However, this command only supports three file
equation options: the file name, the final disposition (;TEMP or ;SAVE),
and the disk volume or volume class (;DEV= DISC or ;DEV=<DISC LDEV
NUMBER>). All other file equation options are ignored.
The file disposition of targetfile defaults to that of sourcefile. For
example, if sourcefile is TEMP, targetfile is created TEMP. If sourcefile
is PERM, targetfile is created as PERM. This file disposition can be
overridden by using a file equation. This is one of the three options
supported for file equations.
All file access attributes of the source file, including ACDs (access
control definitions) are duplicated for the target file.
If a source file has an ACD, the ACD is copied to the target file. If a
file does not have an ACD, and it is copied outside an MPE group, it is
automatically assigned an ACD.
CM files and temporary files cannot be copied to HFS directories.
Use
This command may be invoked from a session, a job, a program, or in
BREAK. Pressing Break aborts the execution of this command and purges the
targetfile.
The COPY command can be invoked in BREAK and does not suffer from process
creation overhead.
Examples
To copy ABCD.logongroup to EFG.logongroup, enter:
COPY ABCD, EFG
To copy ABCD.logongroup to ABCD.newgroup, enter:
COPY ABCD, .newgroup
To copy ABCD.grp to ABCD.logongroup, enter:
COPY ABCD.grp
In the next example the file MYFILE.PUB.SYS is copied to MyFile under the
current working directory (CWD). Note that the target file name has to
have the dot and slash (./) prefix.
COPY myfile.pub.sys, ./MyFile
In the next example, the file File1 under the CWD is copied to MYFILE.PUB
in the current account.
COPY ./File1, myfile.pub
In this next example, file1 in directory dir0 is copied to file2 in
directory dir1.
COPY ./dir0/file1, ./dir1/file2
In the following example, the file TEST has a lockword which is the word
LOCK. The file is copied into file1 in the dir0 directory.
COPY TEST/LOCK, ./dir0/file1
