It's on the menu on the FrontEnd tool (i.e. !ASM) - enter "z1" into the
"Pragma" writable menu item.

I thought about supporting SWI names, but finally decided against it (for
no particularly good reason, I think...). Whenever I'm using ASM, I
tend to have all the SWIsI'm interested in defined in another file that
I then INCLUDE.

1.5MB of source code in a single file isn't what I'd call smallish, but
YMMV.

ADRL is on the list of things to look at, if/whenI get round to doing
more work on ASM (which will probably happen when I get my ARMini).

It was always intended to use the standard Acorn linker for this.
Again, I though of providing a switch to output an absolute or a
Utility, but unfortuntely it's quite a lot of work (I didn't see the
need until about V3, but which time the fundamental program
architecture meant that retro-fitting it wouldn't be easy).

Sorry, I don't follow this. What are you trying to do?

I'm can't recall whether it's in the documentation or not, but a macro
I commonly use is:

          MACRO  EXTERNAL,funcname
          DCSZ   @funcname
          ALIGN
          DCD    ((( size(@funcname) >> 2) + 1) << 2) + &ff000000
          EXPORT funcname
funcname: ENDM

which look pretty gross, but allows me to use, for example:

          EXTERNAL   plotcell

to create a standard C-type function name block that is recognised by
DDT, etc.
