- ARCHIVE Magazine Index Data for ARCSCAN II or III Filing Systems
- ================================================================
- [C] E.W.Ayers : Sept 1992 update to 5.9.92
-
- ARCSCAN is a trademark of RISC Developments Ltd.
-
- NOTE - ARCSCANIII
-
- RISC Developments' most recent version - ArcScanIII - is now multi-tasking.
- It is fully compatible with ArcScanII, and the ARCHIVE ArcScan files may be
- installed in ArcScanII or ArcScanIII and updated in the same way,
- as described below.
-
-
- 1. Organisation of ARCSCAN II & III
-
- ARCSCAN II & III provide for two types of files:
-
- Type 0 Magazine Files - With regular Volume and Issue numbers
- Type 1 Others
-
- The files are held within Directories, and a !Custom file tells ARCSCAN
- what files to offer in its menu display, where to find them, and how to
- display the information contained in them. To add new sets of data to
- ARCSCAN, the appropriate directories must be created to contain the data,
- and the !Custom file must be extended to specify them.
-
- Once this has been done, files may be updated/extended, or further files
- may be added to any existing DIRECTORIES. Provided they conform to the
- format prescribed in the !Custom file, no further changes to the
- latter will be needed.
-
-
- 2. Data on this Disc
-
- The ARCHIVE data on this disc includes three sets of files:
-
- ARCHIVE Magazine contents - Type 0
- - Directory 'Archive'
- - Files ARvol05 (Vol5, 1-12)
- ARCHIVE Monthly Discs - Type 0
- - Directory 'ArDiscs'
- - Files Advol05 (Vol5, 1-12)
- ARCHIVE Care/Shareware Discs - Type 1
- - Directory 'ShareCare'
- - Files Careware (Nos 1-16)
- Shareware (Nos 0-47)
- WIMPed (1 disc)
-
- To add any of these to your ARCSCAN disc, or to update it, it is necessary
- only to make any appropriate changes to the !Custom file (see below), and
- then to copy the relevant DIRECTORY, along with its files, replacing any
- existing directories bearing the same names.
-
-
- 3. The !Custom File
-
-
- 3.1 The Length parameter
-
- The !Custom file provides for specifying the maximum length of each entry
- in a file, and this is used to organise the 'paging' of the ARCSCAN
- display. For the Type 0 files above, the length is set to 6, so that
- several entries appear on each 'page' of the display. For the Type 1 file
- above, the length is set to 25 (the maximum allowed), so that the display
- shows one disc at a time. Setting this parameter wrongly, or exceeding the
- specified length for an entry, may result in parts of a record scrolling
- off the ARCSCAN display or being overwritten before they can be read.
-
-
- 3.2 Modifying the !Custom file
-
- **** BACKUP your ARCSCAN Disc before proceeding! ****
-
- To modify your !Custom file, get !Edit installed on the DeskTop Icon Bar.
- Insert your ARCSCAN disc, and open a filer window. HOLDING DOWN SHIFT,
- double-click on !ArcScan to open a sub-window, which should contain the
- !Custom file. Drag this to !Edit. The latter should open a window
- displaying the file contents. Click MEN (centre button) on this window,
- and select Edit -> CR-LF, which should make the file readable.
-
- Go to the foot of the list, using the scroll bars, and examine the last
- block of entries - it will start with '#' plus a number. NOTE THIS NUMBER
- - your entry will be the next number. At the end of the file you should
- find '##'. Position the cursor (SELect on the mouse pointer) to the
- immediate LEFT of this entry, and press RETURN. This should insert a blank
- line before the '##' file terminator. Move the cursor up to the start of
- it.
-
- You now have to key in the entries for your new data. The formats are
- shown below for each of the three data sets. You may choose to enter just
- one, two or all three, but each entry must be matched by later creating
- the appropriate directory, else ARCSCAN is liable to have a nervous
- breakdown!
-
-
- 3.3 New Entries in !Custom file
-
- The tables below show the entries for each of the three data sets. The
- parameter shown as <n> is to be replaced by the next entry number (without
- the '< >' ). The tabulated entries should be inserted between the last
- existing entry and the end-of-file marker '##', with no blank lines,
- extra spaces or other characters. NB no RETURN after the last item in the
- list!
-
-
- ***SPECIAL NOTE***
-
- If you have already entered the 'ShareCare' directory and data from
- earlier discs, please check your !Custom file complies with the form given
- below, as the LENGTH parameter has had to be altered to accommodate the
- larger number of items on some later discs.

-
- 3.4 Saving the Amended !Custom File
-
- Now again select Edit -> CR-LF by the MEN button, to compact the data.
- Click MEN on your !ArcScan sub-window, select 'File !Custom -> ' and then
- the delete option to remove the old file. Click MEN on the !Edit window
- and select SAVE which will open a save box and an Icon. Check that the box
- still shows the filename as ....!Custom, and drag the Icon to your
- !ArcScan sub-window.
-
-
- 4. Loading Data Files
-
- This is merely a matter of copying from this disc into your !ArcScan
- sub-window those directories that you have specified in the !Custom file.
- If you have earlier directories bearing the same names, these should first
- be deleted as described in section 3.4 for the !Custom file.
-
- The copying may be done by leaving the DeskTop and using *COPY with the
- appropriate pathnames (and Option 'P' to prompt disc changes if you have
- only a single floppy drive).
-
- The easier way however is to stay in the DeskTop and create (temporarily)
- a RAM Disk. Click MEN on the 'A' icon at the right of the icon bar. and
- select 'Task display'. A window will open showing memory allocations.
- Scroll down until you can see 'RAM disc'. Click SEL to the right of this
- and drag a red bar out to give, say, 256 K of RAM disk. Open the RAM disk
- filer by clicking on the icon that should now be visible at the left of
- the icon bar.
-
- Now insert this disk and open the filer window containing the directories
- you want. Drag the required directory to the RAM Disk window (it will
- carry all the contained files with it).
- Re-insert your ARCSCAN disk and re-open the !ArcScan sub-window (remember
- to hold down SHIFT!).
- Drag the directory from the RAM disc window back into it.
-
- You should now be in business, and double clicking on the !Arcscan icon in
- the MAIN ARCSCAN window should start ARCSCAN up. Your new directory should
- now appear in the list (On ARCSCANII, click on 'NEW DATA' to display this).
- The right-hand window should confirm the files actually loaded.
