"As $maxrecords is a positive integer, you loop condition will always be true"... ...means... "As $maxrecords > 0, you loop condition will always be true" Yes, $maxrecords is a positive integer, but that's not the only reason why the condition could be true. I think that something like "As $maxrecords is not zero" would be more informative. If x = $maxrecords, v = value (instead of condition) and > means 'implies', then we can express the statement above mathematically as v = 1 if x > 0 > v = 0 if x <= 0 This is clearly incorrect because we know v = 1 if x < 0, x > 0 i.e. v = 1 if x != 0 So if v is a function of x, where the range of f(x) is f(x) = 1, then for example f:x > x/x for x != 0 and v = f(x) = x/x for x is IR, x != 0 Jane. Think negatively map{$,%(5>>1)^0?push@y,$_:unshift@y,$_}sort(Hacker=>another=>Perl=>Just);for(1&1=>10){push@y,shift@y}print"@y"
