Maximizing AMOS Professional

This is a little guide for the Amiga developers who use AMOS Professional (for convenience, "AMOS" from now on). It provides information and tips to circumvent some issues of AMOS and to produce better code.
It was born in 2023, when, for personal use, I started documenting the quirks of AMOS that I had found and the tricks I had come up with over the years. Eventually, noticing that AMOS is used more than I had imagined, I thought that it could be useful to other developers as well, so I improved some explanations and added new ones, added some examples, reorganized the contents and converted the document from plain text to Amigaguide.
This guide is by no means a complete bible, as surely there are things that I have never stumbled upon (due to my not using certain features and to the systems I work on) and things that I have forgotten; but it will (most likely) be updated if/when I discover something new or I remember about something. Also, the examples provided do not cover all the possible cases - it is up to the reader to fill the gaps and experiment.
This guide is meant to cover only the software originally published by Europress, but chances are it mostly applies also to later/patched versions.
