Re^2: Perl interpretor for conditional operator "?"

Hello Dave, Thanks for detailed explanation. "The sixth line checks to see if $a is less than $b. It should output the content of @x" I'm newbie, as per my understanding here after expression evaluation @x will be assigned to $var in scalar context and print the no of elements in the array, however it is printing content of array.

You misunderstand. Perl makes a difference between `@x` and `"@x"`. `$count = @x;` [download] will assign the number of elements in `@x` to `$count`. `$list = "@x";` [download] will assign string with all elements of `@x` separated by comma to `$list`. See perlop for the stringification/interpolation of arrays and the assignment operator.	[reply] [d/l] [select]
