The Sinclair QL Forum

Hi,

I have finished all the updates, just looking at comestic changes.

I have got Andy other book Assembley Language on the QL OCRed just needs formatting in Libre Office.

Hi,

I gave completed the formatting if Andy's book Assembley Language in the QL,.

Just needs proof read, if any one is interested?

Hi,

Here is the completed book: Please bear in mind that the book was written on the rel;ease of the QL, when on FB Roms were available and there has been many bug fixes since then.

I have tested the SuperBASIC listing of the Disassembler in Superbasic: JS,JM, Minerva v1.98 and SMSQ/E v3.38 v3.38, seems to work, though very primitive.

The assembly listings are untested and there for reference.

This book is not submitted to Gihub as the QDOS Companion.

Thank you, for all your efforts, Derek!

Thanks Derek, I still have a hardcopy of this book but it's starting to fall apart now

Unfortunately, some errors in the original book have been carried over to the digital version. These are from my annotations:

• Page 108: EXG mode bits 10001 are of course for Dx,Ay not Dx,Dy
• Page 112: LEA instruction opcode was missing in the original but the correct opcode is 0100xxx111mmmrrr where xxx is the address register in the second operand
• Page 116: the size bits for the MOVE instruction should be 01 for byte, not 00.
