 ====== McGraw-Hill's 68000 Assembler ======

[[qlwiki:QL Assembly Language Programming]] is an advanced technical guide to 68000 assembly language and QDOS.

The book was written by Colin Opie with the assistance of Tony Tebby and is intended for use with McGraw-Hill's 68000 assembler / editor package, which was sold separately for £29.95

The book covers the 68000 processor itself, with its instructions and addressing modes, QDOS calls and has a number of chapters full of example programs.

McGraw-Hill's 68000 editor is written in SuperBASIC. Its line management works with an array. To add and/or delete lines, the editor uses a resident extension

<code>
ROOM_BIN
</code>

containing two resident procedures


<code>
MAKE_ROOM
TAKE_ROOM
</code>

written by Tony Tebby, which is used to insert ("MAKE_ROOM") or delete ("TAKE_ROOM") a line within the array "on the fly" without losing content. This extension seems to be the first one used for such purposes, written in 1984.

ROOM_BIN was later used by Tony Tebby's own "inhouse" editor "sedit", and "sedit" (which seems to be the prototype for the McGraw-Hill editor) was much later rewritten by Ralf Reköndt with new resident heap extensions and released as "S_Edit", marketed by Dilwyn Jones, now freeware.
