- BIN( is the addr at which the compiled binary will live. It is
- often 0.
-
- ORG is H@ offset at which we begin spitting binary. Used to
- compute PC. To have a proper PC, call "H@ ORG !" at the
- beginning of your assembly process. PC is H@ - ORG + BIN(.
-
- Labels are a convenient way of managing relative jump
- calculations. Backward labels are easy. It is only a matter or
- recording "HERE" and do subtractions. Forward labels record the
- place where we should write the offset, and then when we get to
- that point later on, the label records the offset there.
-
- To avoid using dict memory in compilation targets, we
- pre-declare label variables here, which means we have a limited
- number of it. For now, 4 ought to be enough. (cont.)
