when you say "Acme interface" i don't know whether you mean the Acme
user interface or the Acme program (filesystem) interface.

you've chosen a task that's possible, but not elegant from the user
interface:  right button click on the text:
	:5-#0+#4,5-#0+#8
or alternatively:
	:5-#0+#4;+#4

you can give an arbitrary sam-style address there.
given that the Limbo compiler holds file positions in line.charpos
format, i was considering adding a hack to my local acme
that would understand:

	:5.4,5.8

and then the compiler could spit out more detailed positions
that acme could understand (having the compiler spit
out:

	file.b:100-#0+#20,101-#0+#30: some error

seems a bit uncomfortable).
if you want to do this through the filesystem interface,
write the address to the addr file, and write "dot=addr" to
the ctl file.

read the manual.

  cheers,
    rog.
