!Help

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
The !Scrap application provides somewhere for an application to temporarily
store documents and other information which is being transferred to another
application.

If an error message of the form "Can't transfer file (use *Set Wimp$Scap
<filename>)" is given by an application this means that the !Scrap 
application has not yet been seen by the system.  You should open a
directory display containing !Scrap then try the operation again.

If the message "Protected Disc" is produced when trying to transfer
information between applications it is probably the case that the !Scrap
application is on a floppy disc which is write protected.  To be useable it
must be possible for an application to write into the !Scrap application;
this means that it cannot be used on a write protected floppy disc or if it
is in a read-only location on a network.  You need to copy !Scrap to a
writable location, then double click the new !Scrap to cause the copy to be
used.

Some applications also use !Scrap to store other temporary information
(information which is not being transferred to another application).  These
applications may need !Scrap to have been seen before they are run.
