Curiously, TeXShop's Help panel recommends %!TEX in some places, but % !TEX in others.

Howdy,
In TeXShop, at least, any of the forms
%!TeX ...,
%%!TeX ...
and
% !TeX ...
will be accepted. The first, original form had an objection because some PostScript interpreters in printers too %! as the first characters in a file to mean that it was a PostScript file (that is wrong, it is supposed to be %!PS and they were being lazy but there is not much one can do about that). The second version, with the double %%, was invented by me since it solved the ``problem'' with the first version. The official version is the third one, with the space.
Good Luck,
Herb Schulz
