The series by Roy Warner on Assembly Language is proving of interest, particularly as I have recently entered a useful program from the Acorn User dated September 1987 called ADFS File Finder by David Spencer. Unfortunately, despite very careful checking, it still gives a checksum error. Any ideas? Will the series be covering checksums? I would be interested, for one.

Perhaps Roy could be persuaded to write a piece on this subject...
