Note that the arguments each have a maximum length of 255 characters.
i checked this out back in my skiddie-with-eval days and found out that, in fact, the real limit is this:
you can only send 255 bytes (~255 characters) counting all information sent. the real number is 256 i think, but it trims one off for the id of the servercmd (commandtoserver(
'blah' <-- tagged field, sent as integer (id))
Type this into your console:
$f = new fileObject();
$f.dump();
$f.delete();
or even
new fileObject(f);
f.dump();
f.delete();
