Enter into a classic sheet.

Using the mouse click on the 1st bracket after 'arctan'

That marks the whole expression.

Copy to clip board.

Go to a new section and paste.

That will insert arctan(X,Y)

Now immediately say:

A:=%;
x:=op(1,A);
y:=op(2,A);

Quite lame, yes. But: done.

How about this, where `ee` is your big expression with the arctan call in it.

stuff := seq([op(t)],t in indets(ee,specfunc(anything,arctan)));

stuff[1];
stuff[2];

Apparentely, it works.

Thank you, very much.
