Routines/ReadMe
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

Acorn-specific usage instructions
---------------------------------
An extra option ('I') has been added to the Acorn port: if it is specified
zip will not consider Image files (eg. DOS partitions or Spark archives when
SparkFS is loaded) as directories but will store them as single files. This
means that if you have, say, SparkFS loaded, zipping a Spark archive will
result in a zipfile containing a directory (and its content) while using the
'I' option will result in a zipfile containing a Spark archive. Obviously
this second case will also be obtained (without the 'I' option) if SparkFS
isn't loaded.
When adding files to a zipfile; to maintain FileCore compliance, all
files named "file/ext" will be added to the archive as "file.ext".
This presents no problem if you wish to use unzip to extract them on any
other machine, as the files are correctly named. This also presents no
problem if you use unzip for RISC OS, as the files are converted back to
"file/ext" format. The only problem appears when you use SparkFS to
decompress the files, as a file called "file.ext" will be extracted as
"file_ext", not what it was added as. You must be careful about this.
Case Specific. Depending on how you type the command, files will be added
exactly as named; in this example:
*zip new/zip newfile
*zip new/zip NewFile
*zip new/zip NEWFILE
will create an archive containing 3 copies of the same Risc OS file 'newfile'
called 'newfile', 'NewFile' and 'NEWFILE'. Please be careful.
The Acorn port conserves file attributes, including filetype, so if you
zip on an Acorn, and unzip on another Acorn, filetypes will be maintained
precisely as if you used uncompressed files. If you de-archive on another
machine (PC, Mac, Unix etc..), filetypes will be ignored, but the files
will be identical despite this. This feature is fully compatible with
SparkFS, so zipfiles created by zip will be correctly uncompressed (including
filetype, etc.) by SparkFS.
An additional feature went into this port to cope better with C-code
and extensions. This allows the acorn files "c.foo" to be added to the
archive as "foo/c", eventually appearing in the archive as "foo.c", allowing
for better handling of C or C++ code. Example:
*Set Zip$Exts "dir1:dir2:dir3"
*zip new/zip dir1.file
*zip new/zip dir2.help
*zip new/zip dir3.textfile
Creates a zipfile new/zip, with entries file.dir1, help.dir2, textfile.dir3.
The usual settings for Zip$Exts are "h:o:s:c", allowing C code to be added
to the archive in standard form.
A final note about the Acorn port regards the use of the 'n' option: this is
used to specify a list of suffixes that will not be compressed (eg. .ZIP,
since it is already a compressed file). Since RISC OS uses filetypes instead
of suffixes, this list of suffixes is actually considered as a list of
filetypes (3 hex digit format). By default, zip doesn't compress filetypes
DDC (Archive, Spark or Zip), D96 (CFS files) and 68E (PackDir).
