I have a question - is it possible to append to a macro variable? E.g.:

SetMacro foo <bar>

Now I want to append to foo, to get the effect of:

SetMacro foo <bar>,<thing>

but in a way that doesn't require me to know the current value of foo.
SetMacro foo <foo>,<thing> gives you infinite recursion, while
Set foo <foo>,<thing> stops it being a macro. I think it's impossible (without
writing a program), but am I right?

  Another question, while I'm at it - does anyone know if the use of sprite
memory by SparkFS is compatible with MemFS? Incidentally, if you do use these
together note that memfs redirects <wimp$scrapdir> into itself by default, so
redefine the SparkFS temporary file to avoid problems!
