- ARCHIVE Magazine Index Data for ARCSCAN III Filing System
- =========================================================
- [C] E.W.Ayers : Aug 1994 update to 03.08.94
-
- ARCSCAN is a trademark of RISC Developments Ltd.
-
-
- 1. Organisation of ARCSCAN III
-
- ARCSCAN III provides 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'
- - File ARvol07 (Vol7, 1-11)
- ARCHIVE Monthly Discs - Type 0
- - Directory 'ArDiscs'
- - File Advol07 (Vol7, 1-11)
- ARCHIVE Care/Shareware Discs - Type 1
- - Directory 'ShareCare'
- - Files Careware (Nos 1-21)
- Shareware (Nos 0-51)
-
- If you already have one or more of these directories, then the appropriate
- files can be simply copied into them (any earlier version of the SAME file
- will be overwritten, but files for earlier volumes will be unaffected).
- If however a directory is not present you will have to extend the !Custom
- file (see below) and create the required directory first.
-
- 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!

- 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. Create new directories with the names you have
- specified and copy the data files into them as indicated in para. 2 above.
