Dru, `push @nums , @nums1, @nums2; # or to skip arrays all together print map { ($_ > 9 ? '1234560' : '1321343') . "$_\n" } 1 .. 99;` [download] Cheers - L~R	[reply] [d/l]

Parentheses are your friends. `@nums = ( (map q\|1234560\| . $_, 1..9 ), (map q\|1321343\| . $_, 10..99) );` [download] -- Chip Salzenberg, Free-Floating Agent of Chaos	[reply] [d/l]

That's how I'd write it too... However, I'd like to point out that `map` actually is a function, so you can use parentheses in the way tha is common for any other function: `@nums = ( map(q\|1234560\| . $_, 1..9 ), map(q\|1321343\| . $_, 10..99) );` [download]	[reply] [d/l]

But I'm not fond of the `map EXPR` syntax. A block of executable code should look like a block of executable code, and be different from the always-evaluated input list. Or so it seems to me. Unfortunately I recently found out that `map BLOCK` is actually a bit slower than `map EXPR`. I might fix that one of these days. -- Chip Salzenberg, Free-Floating Agent of Chaos	[reply] [d/l] [select]

Are `@nums1` and `@nums2` really going to contain that data? That's a really bizarre way to generate a list of consecutive numbers. This reads better in my opinion: `@nums = (12345601 .. 12345609, 132134310 .. 132134399);` [download] This'll be fine unless the integers are too big and become floats. blokhead	[reply] [d/l]
