This is the authoritative guide to the Sinclair QL System. It provides a complete introduction to QDOS and assumes no previous knowledge of operating systems or 68000 assembler.

Multi-tasking and other powerful features of QDOS are fully explained together with numerous examples to illustrate their uses. A complete listing of the QL Experimentor program is included, which allows many of the facilities provided by QDOS to be tried out from SuperBasic.

No programmer of the QL can consider not owning a copy of this invaluable reference manual.

Please note there is writing on the first page of the book.
