Converting and Copying Files
DISCMGR provides a command for converting files from DOS to MPE and vice
versa. These commands (DOSTOMPE and MPETODOS) are especially useful if
you use both HP 3000 and PC programs, and want to move data from one to
the other.
There is also a COPY command to copy files from one shared disc or
directory to another.
These commands in their basic syntax are quite easy to use, and the use
of wildcards and command options can make them very powerful.
First, let's look at the basics.
To convert file(s) from DOS to MPE:
1. Start DISCMGR.
2. Connect to the shared disc that contains the file(s) you want to
convert.
3. Enter the following command:
DOSTOMPE dosfilename TO mpefilename
The conversion begins without further prompting. When it is
complete, the following message appears, where n is the number of
files converted or copied:
n file(s) converted.
For example, to convert the shared disc DOS file TEST1 to an MPE
file with the name MPETEST1, enter:
DOSTOMPE TEST1 TO MPETEST1
To convert file(s) from MPE to DOS:
1. Start DISCMGR.
2. Connect to the shared disc to which you want to convert the MPE
file.
3. Enter the following command:
MPETODOS mpefilename TO dosfilename
The conversion begins without further prompting. When it is
complete, the following message appears, where n is the number of
files converted or copied:
n file(s) converted.
For example, to convert the MPE file called JUNRPT to a DOS shared
disc file with the same name, enter:
MPETODOS JUNRPT TO JUNRPT
To copy a file from one shared disc or directory to
another:
1. Start DISCMGR.
2. Make sure uses are established for the shared disc(s) you want to
use.
3. Enter the following command:
COPY [drive:] dosfilename TO [path]newdosfilename
For example, to copy the file SALES from S: to the subdirectory
ACCTNG on the X: drive, you would enter this command:
COPY S: SALES TO X:\ACCTNG
Since a new filename is not included, DISCMGR creates the new
filename with the same name as the old filename.
Using Wildcards
Now that you know the basic commands, let's take a look at how MPE and
DOS wildcards let you select multiple files for copy or conversion.
You can use MPE wildcards in the source filename in the MPETODOS command
and in the target filename in the DOSTOMPE command.
MPE Wildcards
Symbol Useage
--------------------------------------------------------------------------------------
@ Specifies one or more alphanumeric characters in an MPE filename.
Similar to the * wildcard in DOS, except that you can enter other
characters after the @ symbol when specifying the MPE source file. For
example, if you enter A@S, all files that begin with A and end with S
will be selected, for example, AS, ABS, ALPHAS.
# Specifies one numeric character in an MPE filename. No DOS equivalent.
? Specifies one alphanumeric character. Identical to ? in DOS.
You can use DOS wildcards in the target filename in the MPETODOS command,
in the source filename in the DOSTOMPE command, and in the source and
target filenames in the COPY command.
DOS Wildcards
Symbol Useage
--------------------------------------------------------------------------------------
? Specifies a single valid character in a DOS filename.
* Specifies one or more alphanumeric characters in a DOS filename. For
example, the filenames *.* and * equate to all files. The filename *.
means all files without extensions. Any characters entered after the *
symbol will be ignored. For example, if you enter A*S, the S will be
ignored and all files that begin with A will be selected.
DOS filenames can contain characters that are invalid in MPE filenames.
For example, MPE filenames cannot contain extensions or certain special
characters such as $ or _. DISCMGR produces valid MPE filenames by:
* Dropping DOS file extensions
For example, the DOS filenames REPORT.M1 and MYFILE.EXT would be
changed in MPE to REPORT and MYFILE. Make sure your files have
different filenames before you use this command or all files will
not be converted. If you tried to convert the files MYFILE.ABC
and MYFILE.DEF by using the wildcards M*.*, only the last file
would be available in MPE. (Both files would be converted, but the
last one converted would write over the first file.)
* Eliminating invalid MPE characters
For example, the DOS file SAMPLE$1 would be changed in MPE to
SAMPLE1.
* Providing generic filenames when DOS filenames are composed
entirely of invalid MPE filename characters
In an interactive session, DISCMGR prompts you for a unique
filename when a valid MPE filename cannot be produced.
In batch mode, DISCMGR creates generic filenames in the format
FILEnnnn, where nnnn is a number from 0001-9999. For example, the
DOS filename 123&&##%.EXT would be renamed in MPE to FILE0001.
* Not converting a file when a duplicate filename exists
In an interactive session, DISCMGR prompts you for a filename when
it encounters a duplicate filename (and you haven't specified the
REPLACE option).
In batch mode, DISCMGR does not convert duplicate files unless you
specify the REPLACE option.
Examples
Let's say you want to convert the following MPE files to DOS files ending
in the extention .GAL:
READ01R
READ02R
READ03R
You could enter the following command:
MPETODOS R@##R TO *.GAL
The resulting DOS files would be:
READ01R.GAL
READ02R.GAL
READ03R.GAL
You use the ? wildcard in a similar fashion. Let's say you want to
convert the following DOS files to MPE files that begin with Z and the
fifth letter of the filename is Z:
MYTEXT
MYREPT1
MYTEXT2
Enter the following command:
DOSTOMPE M* TO Z???Z@
The resulting MPE files would be:
ZYTEZT
ZYREZT1
ZYTEZT2
Options
Several options are provided with the copy and conversion commands to
give you further control over the conversion, such as listing files as
they are converted, or defining the record size. Three of these options
(SHOW, MOVE, and REPLACE) can be used with all three copy and conversion
commands. More than one option can be used in a single command, except
that you cannot use both ASCII and BINARY in the same command.
SHOW To see the filenames as they are converted, use the
SHOW option:
DOSTOMPE [drive:] dosfile TO mpefile;SHOW
For example, let's say you want to convert all DOS
files beginning with RE to MPE, and you want to see
the files as they are converted. You would enter:
DOSTOMPE RE*.* TO @;SHOW
The resulting display might be:
READ1 --- READ1
REFILE1 --- REFILE1
REFILE2 --- REFILE2
RENOTES.TXT --- RENOTES
MOVE To actually move a file from MPE to a shared disc,
use the MOVE option. When you specify MOVE, the
source file is purged after the conversion. For
example, the following command moves the MPE file
TEST to a shared disc, removing the MPE file
entirely:
MPETODOS TEST TO *;MOVE
REPLACE To write over existing files with the same name,
use the REPLACE option. For example, to copy the
files DOSFILE1.EXT through DOSFILE9.EXT on the J:
shared disc to the M: shared disc, replacing any
existing files with the same names, enter this
command:
COPY J:DOSFILE*.* TO M:*.*;REPLACE
If you do not specify the REPLACE option and a file
with the same name already exists, DISCMGR asks if
you want to replace it. If you enter Y, DISCMGR
replaces the existing file. If you type N, DISCMGR
prompts for a new filename.
Command-Specific Options
BINARY The DOSTOMPE command lets you specify binary DOS
files, such as a file created with HP Drawing
Gallery or Charting Gallery. For example, to
convert the Gallery file called PICTURE.GAL to MPE,
enter this command:
DOSTOMPE PICTURE.GAL TO @;BINARY
ASCII The DOSTOMPE command lets you specify ASCII DOS
files. For example, to convert the DOS file
TEXT1.EXT to MPE in an ASCII format, enter this
command:
DOSTOMPE TEXT1.EXT TO @;ASCII
ASCII is the default value, so if you do not
specify a file enter, ASCII files will be created.
RECSIZE The DOSTOMPE command lets you specify the record
size with a negative number for bytes or a positive
number for words of the target file. If you
specify the BINARY option, the default value is
-256. If you do not specify the BINARY option, the
default value is -80. For example, to specify a
record size of 120 bytes, enter this command:
DOSTOMPE TEXT1.EXT TO @;RECSIZE=-120
TREE The COPY command lets you specify TREE, which lets
you create a DOS tree structure on the target
shared disc. Let's say you want to copy the files
on the J: shared disc in the subdirectory ADMIN to
the N: shared disc. In order to maintain the DOS
tree structure, you could enter:
COPY J:\ADMIN TO N:\subdir1*.*;TREE
Temporary Connections
There are two more ways you can use the copy and conversion commands. If
you haven't established a connection to the shared disc you want to use,
you can access the shared disc temporarily by designating the MPE group
and account or the sharename in the command. This temporary connection
lasts only as long as the command needs to execute.
For example, to convert a file in a shared disc called FILE.TXT to an MPE
file called FILE1 when you are not connected to that shared disc, you
could enter:
DOSTOMPE MPE: \account\group\FILE.TXT TO FILE1
This connects to the shared disc temporarily by identifying the account
and group containing the shared disc.
You could also enter:
DOSTOMPE !sharename [password]:FILE.TXT TO FILE1
This connects to the shared disc temporarily by identifying the shared
disc sharename.
NOTE Your ability to use the \account\group method to connect to a
shared disc depends on your HP 3000 capabilities. If you have
System Manager (SM) capability, you can connect to any account and
group. If you have Account Manager (AM) capability, you can
connect to any group in your account. If you have basic
capabilities, you can connect to the logon account and group.
