AutoSource (Po85)

For BBC B/B+/M/C/E with SWR
(C) BAU January 1992 & March 1988

I had to patch this a little as the end of the file was corrupt.
It seems PROCsum was missing from the end so I used the checksum routine that David uses in the Acorn User 128DFS extension ROM.
Unfortunately it doesn't seem to be quite the same, so if anyone has the original source... :-)

But it compiles and seems to run OK, but be warned.
