well counting left and right brackets is fundamental programming, and
someone who makes such a basic mistake *and doesn't see it* is pretty
new to the game.

As I said, the ! operator is less intuitive than '==0' to me anyway,
though after years of C its second nature.

by definition at this particular game you ARE a noob. or you wouldn't
have missed the unmatched brackets. I ceratyinly d0nt see that as any
reflection on unerlying intelligence...teh first program I wrte in
assembler I copied exactly out of a book. It didnt assemble. Then I took
the line numbers out. It still didn't assemble. Then I removed all
leading spaces from every line. That did work. That took two 4 hour
sessions of frustration.

I wasn't stupid. I simply had no idea, nor did the documentation say,
that line numbers and spaces were tabu.

Ineptocracy

(in-ep-toc’-ra-cy) – a system of government where the least capable to lead are elected by the least capable of producing, and where the members of society least likely to sustain themselves or succeed, are rewarded with goods and services paid for by the confiscated wealth of a diminishing number of producers.
