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.

File contents
--------------------------------------------------------
FNshell_OSCheckModuleVersion()
Params =>
str module name
real version nr required
<=
bool TRUE or FALSE
Use this routine to check whether a
certain version (or later) of a specific
module is installed.
--------------------------------------------------------
FNshell_OSCheckVersion()
Params =>
real version nr required
<=
bool TRUE or FALSE
Use this routine to check whether RISC
OS 3 is installed for example. The
routine returns FALSE if the OS version
requested (or a later version) is not
found.
--------------------------------------------------------
FNshell_OSVarExists()
Params =>
int workspace buffer
str os variable name
<=
bool TRUE or FALSE
--------------------------------------------------------
FNshell_OSVarGetVal()
Params =>
int workspace buffer
int size of buffer
str os variable name
bool expand flag
<=
str value of variable
--------------------------------------------------------
FNshell_OSReadCommandArg()
Params =>
int option (must be 0 or 1)
<=
str command string
--------------------------------------------------------
FNshell_GetCmdLineArgs
Params =>
None
Returns the command line used to start the program
excluding the program name itself. If an alias has
been set up for the filetype with Set
Alias$@RunType_xxx then this call will return the
name of the file that was double clicked on to start
the application.
