Re: STATUS Cell Alignment

This is how I cell-aligned tasks (data stack, return stack, and STATUS ). I
was able to reuse Forth Inc's BACKGROUND but don't know a way around
copy/pasting TERMINAL from Tasker.f (yours may differ) so terminal tasks get
so aligned:

INTERPRETER

: BACKGROUND ( nu ns nr -- )
>R >R >R
    SAVE-SECTIONS
      UDATA ALIGN
    RESTORE-SECTIONS
  R> R> R>
  BACKGROUND ;

: TERMINAL ( n -- )
   |NUM| + |PAD| + RESERVE \ Space for NUM, PAD, HERE
   |U| |S| |R| |TIB| + BACKGROUND , ; \ Allocate task, save its HERE

Depends on the bus size. If it's 16-bit (very common in 68K systems) or
8-bit
(less common but we've seen it), no problem. If it's 32-bit then you should
align it.
