In order to check if this is the first time the macro has been called
on this page, I can add attributes to the request object - example:

def execute(macro, args):
    n =3D getattr(macro.request, 'TEST_n', 0)
    n +=3D 1
    macro.request.TEST_n =3D n
    return '<b>Number of calls =3D %s</b>' % (n,)

This seems to work OK - but is it acceptable practice? If not, is
there any other way of telling (on a per-render basis) how many times
the macro has been called so far on this page?

(I've not found any formal documentation on how to write a macro, what
APIs are supported, etc. I'm going on experimentation and picking
ideas up from other people's code. Is that the best way, or have I
missed some docs I should be referring to?)

You can use this, but you don't really care how many times the macro is 
called. Use simpler code like this:

def execute(macro, args):
	
	if not hasattr(macro.request, 'mymacro_script_sent'):
		# send the macro once here
		macro.request.mymacro_script_sent = True
	
	# rest of your macro...

Yes, that's what I'd do for this case. The code I posted, counting the
number of calls, was just a test (the macro just displayed the count,
to save me having to worry about whether my script code was doing the
right thing, as well... :-))

Thanks for the confirmation.
