Hello Bernard:

I explain my problem again starting from Adam and Eve:

I have a HP 3000 GX. There is Turbo Image database on it.

I have a PC connected with a copper wire to the HP 3000. I have the
Minisoft 92 on it.

Our institute has an Ethernet network. I can mount a library as J: drive a
the machine DEC Alpha0 (see my e-mail address) from my PC by the "idmount"
program.

Now I can download a plain vanilla HP 3000 file not only to C: drive of my
PC but to the mounted J: drive on the DEC Alpha0 machine.

I want to save the TurboImage database on the HP to the J: drive for
- future migration purposes
- as an alternative backup device to the magtape of the HP3000.

The Turbo Image database consist of privileged files.

I cannot download privileged files by the file transfer utilities of the
Minisoft 92.

If I change the file codes of the Turbo Image database files then they are
no longer privileged files. So Minisoft transfer utilities can open them.

The Turbo Image database files contain essential information in their file
label! I must not lose this information in the backup copy on the
J: drive otherwise I would restore this copy in vain in case of disaster!
In my current test so far I lost the file labels when I uploaded the
copies from the J: drive to the HP3000.

Now, if somebody does not advice a simpler way, I have to do the following
steps in my alternative backup-recovery cycle:


B1. Change the file code of the Turbo Image dataset files to positive.
B2. Dump their file labels to a temporary file, let me call it
DATABASE.LABELS.HP3000.
B3. Download the non-privileged database file to the J: drive.
B4. Download the temporary file containing label information to the
J:DATABASE.LABELS file.

R1. Upload the J:DATABASE.LABELS file to the DATABASE.LABELS.HP3000 file.
R2. Upload the dataset from the J: drive to the HP3000 in non-privileged
form.
R3. Run a home-made program which reads the
DATABASE.LABELS.HP3000 file and reconstructs the original file labels
(except the file code) of the TurboImage database files using FWRITELABEL
intrinsics.
R4. Change the file codes of the restored files to -400-n, as required for
the TurboImage root, ILR, and data files.

My question: How can I avoid steps B2, B3, and R2, R3, respectively?

                                        Regards

                                             Frank

There are 3 kinds of programming errors:  syntactical, semantical and
mystical.
The programmers have to suck up the users just as much as absolutely necessary.
