\... I had no intention

\secondary prompt after I had already entered "end;ls" I figured what the
\hell and entered the second end. What caused this?

Welcome to csh! It's just the way csh works: confusing syntax, buggy parser.
Beware if you want to use anything more difficult than:

	alias	ll	ls -la
	set	history = 20

The `end' statement must either appear alone on a line, or followed by a
semicolon PRECEDED BY WHITESPACE! Everything after the `;' (on the same line)
is PART OF THE LOOP!
Now go home, switch on your turntable and put on some record called `Crying'.
