Documents/OldSWIs
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.

ArcFS 0.50/2.00 Documentation
-----------------------------
Old Software Interrupts
-----------------------
The following Software Interrupts are supported for compatablity with older
versions of ArcFS only. They must NOT be used unless compatability with older
versions is required.
The allocated SWI chunk base is &437C0.
*****************************************************************************
SWI "ArcFS_ArchiveInfo" &437C0
----------------------- ------
On entry: R0=archive number
On exit : R0=pointer to archive name (null terminated)
� R1=pointer to archive pathname (null terminated)
R2=pointer to archive headers (internal use only)
This SWI gives the name and pathname of the archive whose number is given by
R0 on entry. The first archive has number zero. If R0 is zero on exit then
there are not this many open archives.
Unlike previous versions of ArcFS there is no limit to the number of open
archives.
In order to maintain compatability with older versions when constructing a
list of open archives, you should call this SWI repeatedly, with R0=0 the
first time and increasing it by 1 each time. If the SWI returns with R0
pointing to a null string then you should miss out that archive (an empty
slot in previous versions of ArcFS). If the SWI returns with R0=0 then the
list is complete. (This will be when you try to get details of the 6th
archive in previous versions).
*****************************************************************************
SWI "ArcFS_Status" &437C1
------------------ ------
On entry: -
On exit : R0=status (&vvbbffee)
This returns the current status of ArcFS.
vv is &FF for read / write version or &00 for read only version
bb is no. of bits for crunch / compress formats (0 otherwise)
ff is the compression format (see SWI "ArcFS_Compression", below)
The bottom bit of ee is set if file garble is set or clear otherwise. The
other bits of ee are reserved for future expansion.
*****************************************************************************
SWI "ArcFS_OpenArchive" &437C2
----------------------- ------
On entry: R0=pointer to pathname (control terminated)
R1=pointer to name (control terminated)
On exit : R0 & R1 preserved
This SWI opens an archive. Possible errors are 'This archive is already open
with a different name' or 'An archive with this name is already open'.
*****************************************************************************
SWI "ArcFS_CloseArchive" &437C3
------------------------ ------
On entry: R0=pointer to name (control terminated)
On exit : R0 preserved
This SWI closes an archive. Possible error is 'No archive with this name is
open'.
*****************************************************************************
SWI "ArcFS_Encryption" &437C4
---------------------- ------
On entry: R0=encryption method (none=0, garble=1)
R1=pointer to password (control termainated, up to 32 bytes)
On exit : R0 & R1 preserved
This SWI sets the encryption method and password used.
*****************************************************************************
SWI "ArcFS_Compression" r/w version only &437C5
----------------------- ---------------- ------
On entry: R0=compression format (&82,&83,&88 or &FF)
R1=no. bits for &88 and &FF
On exit : R0 & R1 preserved
This SWI sets the data compression format to be used:
&82 Store
&83 Pack
&88 Crunch
&FF Compress
Possible errors are 'Bits range error' and 'Unknown compression format'
*****************************************************************************
SWI "ArcFS_CreateArchive" r/w version only &437C6
------------------------- ---------------- ------
On entry: R0=pointer to pathname for new archive
On exit : R0 is preserved
This SWI creates (but does not open) a new archive.
*****************************************************************************
SWI "ArcFS_Compact" r/w version only &437C7
------------------- ---------------- ------
On entry: R0=pointer to archive name or 0
On exit : R0 is preserved
This SWI compacts the named archive (or that containing the CSD) to removed
gaps left by deletions and file overwrites.
