- Frequently Asked Questions about The Star Commander
-
- Here are some questions I was asked many times and my answers to them. First,
- I'd like to mention that the Commander was not meant to be a multi-purpose
- utility with lots of goodies and that the executable file SCMAIN.EXE is already
- too big. And to advertize my favorite Commander, The Volkov Commander: one of
- the things I just love in it is that there are no redundant functions in it. It
- is as simple as possible. In brain order:
-
- Q: Does the Commander support non-1541 drives?
- A: No, only the 1541 drive family, 1541 compatible drives and the 1541 mode of
- the 1571 drive since the only drive I have is a 1541C drive.
-
- Q: Does the Commander support 40 track disks and disk images?
- A: Not yet. I have no enhancements on my 1541 drive therefore it is hard to
- implement the necessary changes in my copy routines. I've never seen such
- disks in my life but I'll do my best.
-
- Q: The benchmark in the documentation says that copying a whole disk in warp
- transfer mode takes not more than a minute and a half. How is it possible
- then that it's even slower than turbo transfer mode on my machine?
- A: Perhaps, you are using the delay value computed by the internal calibrator
- of an earlier release. The synchronization method has been changed since
- then and you should not use the old delay value. If you have a 386 or a 486
- you should try the default delay value of 12. If you have a 286 then lower
- it; if you have a Pentium then raise it.
-
- Q: Anyway, why do I have to change the delay value every time a new version is
- released?
- A: I'm constantly playing with the transfer routines so that they become more
- and more stable and as fast as possible. When I change the timing then the
- delay value is not valid anymore. Now the timing is done with the hardware
- system timers which is machine independent. To tell you the truth, I still
- have no idea why you have to change the default delay value of 12 at all and
- why doesn't the Commander work for everyone at last...
-
- Q: And what about the other options? Do I have to set all of them again and
- again?
- A: Not anymore. From Version 0.71 beta on the Commander and its external setup
- program are able to read the setup file created by the previous version so
- that you only have to set the new options and those having been changed.
-
- Q: Does the Commander support file images (files with the extension '.P00'/
- '.S00'/'.U00' created and used by PC64)?
- A: Not yet. There is a technical problem: how can you tell the Commander that
- you want the file under the cursor bar to be copied into a file image?
- Create an empty file image and then copy that file into it like with tape
- images? That's not possible because there's no file image without a binary
- file inside it. I have an idea which might help: there could be an option
- 'Into file image' in the copy/move dialog box. By checking it the Commander
- would copy/move that file into a file image (creating it on the fly),
- provided that the destination is a DOS directory. What do you think?
-
- Q: There are some minor but annoying differences between your Commander and
- The Norton Commander. Why?
- A: A personal opinion: when I started using The Volkov Commander, I began to
- hate The Norton Commander. Consider that The Volkov Commander is a single
- 64KB COM file, still it can do what The Norton Commander 3.0 can. It's not
- that overgrown fatware like The Norton Commander has become (not to mention
- that now it has nothing to do with Peter Norton - the best progammer ever -
- and should be called The Socha Commander or The Symantec Commander). I make
- my Commander to be similar to the The Volkov Commander and not to The Norton
- Commander. Admit it that after some hours you got used to the new features
- like pressing Escape turns the panels off, maybe, now you like them...
-
- Q: Will there be a directory editor inside the Commander?
- A: No. However, it's possible that I code a stand alone directory editor for
- disk images.
-
- Q: I hate the colors the Commander uses. Can I change them?
- A: Yes, you can. There is a full color configuration menu in the external setup
- for all screen modes (black & white, color, laptop and monochrome). You can
- also try the prepared palette files that make the Commander look much more
- similar to 'Color 2' of the The Norton Commander and Dos Navigator.
-
- Q: Why doesn't the Commander work under my OS/2, Linux, Windows or Windows'95?
- A: Because it's technically impossible to achieve correct timing under these
- multi-tasking environments: the kernel (the control program of the operating
- system) steals time for monitoring the system messing up the synchronization
- between the PC and the external CBM drive.
-
- Q: Will you do an OS/2, Linux, Windows or Windows'95 version of the Commander?
- A: No, I won't. See above for the reason why the Commander wouldn't be able to
- access a connected Commodore drive under these multi-tasking systems. It's
- no use to run the Commander under them because you would lose one of the
- main features.
-
- Q: I would like an OS/2 version of the Commander for another reason. Running on
- HPFS, it could use the original long CBM filenames and I could forget the
- 8.3 filename limitation of DOS. What do you think?
- A: Such a version of the Commander wouldn't help much with long filenames
- because CBM filenames need to be converted into ASCII. During that many CBM
- characters would be lost because they have no equivalent in ASCII or are not
- allowed in a HPFS filename. Not to mention that I'm not sure if Borland
- Pascal can compile the Commander to run under OS/2... But I'll try it.
-
- Q: I've edited the directory of a disk and then copied it onto my PC with the
- option 'BAM disk copy' checked. The end of the directory was lost. Why?
- Q: I've edited the directory of a disk image and then cleaned it with the
- 'Clean' option in the user menu of disk image panels. Why did I lose the
- end of the directory?
- A: There's a serious problem with Dir Master by Wim Taymans, which is the best
- and most wide-spread directory editor around. When you insert some phantom
- files into the directory (e.g. deleted files whose names make up the logo of
- your group) the size of the directory will grow. When you save it back onto
- your disk or disk image then some new sectors will be filled with the new
- data. But the program forgets to allocate those new sectors therefore the
- disk copier won't copy those blocks and the disk image cleaner will destroy
- all data in them. Validate your BAM with the 'Validate' option in the user
- menu or manually in the disk editor before copying or cleaning. You can also
- switch the option 'Copy full track 18' on and track #18 will be fully copied
- even during BAM disk copy, and for cleaning the disk image use 'Safe clean'
- which does not harm a single byte on track #18.
-
- Q: May I know what language the Commander is written in?
- A: I started coding it in Turbo Pascal 7.0 with Turbo Vision 2.0 but changed to
- Borland Pascal 7.0 a bit later since it had a better IDE and online help.
- When I got the sources of the run-time libraries I began rewriting the user
- interface so that it looks absolutely like The Norton Commander. Many of the
- original Turbo Vision routines were deleted or changed during this process.
- The source of the Commander, the external setup and the internal viewer is
- now at about 850 KBytes - not counting the little utilities I made for
- compiling the online help and other purposes. There are also many assembly
- routines in the source, mainly for data transfer and conversion where speed
- is very important.
-
- Q: Why can't I copy all the files on the disk of my favorite demo?
- A: Probably some files on that disk are phantom files (directory entries with
- no real file data) or have non-standard characters in their name (graphical
- characters or characters that are not even allowed in filenames, like colon,
- asterisk, question mark etc.). The Commander uses the original 1541 DOS to
- open files so it does not support such files either. Rename those files
- using the disk editor or copy the whole disk instead.
-
- Q: Why is it that although I have defined several standard viewers in the file
- SCVIEW.EXT, the Commander still can't use them like The Norton Commander?
- A: Perhaps, you are using the viewers of The Norton Commander 5.0, which
- require data to be passed in a special file instead of a special parameter
- block on the command line. The Commander can only use the parameter block,
- therefore you should use the viewers that came with an earlier version (3.0,
- 4.0 or 4.5) of The Norton Commander.
