How do I obtain an allocated filetype or SWI chunk for my software?
When developing new software, you should try to ensure that any filetypes or SWI calls are unique to your software. This will ensure that your new application doesn’t cause conflicts with any existing software. In order to to this you should apply to RISC OS Open in order to register your application name and any system variables, SWI calls or any filetypes your application may require. The !Allocate application will do this for you, which can be downloaded from http://www.riscosopen.co.uk/content/allocate and your request should be emailed to allocate (at) riscosopen.
