-/* swi
-
- RISC OS swi functions
-
- 1.00 Chris Stretch
-
-
- 1.01 12 May 1999 Laurence Tratt
-
- * Changed swi.error to be a class based exception rather than string based
- * Added swi.ArgError which is generated for errors when the user passes invalid arguments to
- functions etc
- * Added "errnum" attribute to swi.error, so one can now check to see what the error number was
-
- 1.02 03 March 2002 Dietmar Schwertberger
- * Added string, integer, integers, tuple and tuples
