Hi Xin,
I'm all over this. In fact, I'd like any function FOO to be callable with either:
IDL> a = foo()
or
IDL> foo()
In the latter case, the return value is swallowed.
I'm still working on getting buy-in for this, though.

Oh, please don't get me started on the subject of kids today... :-(

pl.pro:

end
IDL> pl,x,y

I always use a=plot(x,y) instead of !null in this case, btw. But still it's not very convenient.
