My first thought is "Is this OR or AND"? And my second thought is "If
this is OR, then what's AND?"
Being dyslexic I'm easily confused that way (seriously, that's the
reason I never use an else-if).

Well, actually,
if(!isset($argv[1],$argv[2],$argv[3])))
is AND.
As it is the same as this:
if( ! ( isset($argv[1]) && isset($argv[2]) && isset($argv[3]) ) )
Which most of us write
if (!isset($argv[1]) || !isset($argv[2]) || !isset($argv[3]))
All three have the same result ;)
Could be for most of you, but that would still be a stumbling block
for me. However, I can always find a way that works.
Cheers,
