| − | | + | |
| − | The <code>Pload</code> instruction takes the first code hunk out of an Amiga executable and copies it into the bank, without even applying its relocations, therefore all code needs to use PC-relative addressing. The <code>Call</code> instruction jumps directly to the start of the bank. The registers (A0, A1, D0, D1, ...) can be set in preparation for a call by setting the <code>Areg()</code> and <code>Dreg()</code> arrays. Extra parameters can also be included with the <code>Call</code> instruction, these are made available to the called function via a stack pointed to by the A3 register.

"AMOS Memory Bank" can mean just "AmBk"-tagged banks, or it can be an umbrella term that also includes AMOS Sprite Bank ("AmSp") and AMOS Icon Bank ("AmIc"). Careful writers may prefer the term "AMOS Bank", instead of "AMOS Memory Bank", when referring to all types of AMOS banks.
