Re^4: 2 D array

So, @row = ((0) x 361); is creating a one-element list whose element is a scalar string of 361 zeros.('0000000000000000 ... 00000')

No. 0 x 361 would do that. (0) x 361 creates a list of 361 zeroes.

>perl -E"say for (0) x 5;"
0
0
0
0
0

>perl -E"say for 0 x 5;"
00000

Yeah, that's a pretty quirky syntax.

Thanks for that correction. I had tested the idea with: `perl -e "print ((0) x 11);"` and saw a line of zeros. I guess printing 11 elements is going to look like a string (`00000000000`) but that doesn't mean it IS a string! Another good reason to use `say` :-)	[reply] [d/l] [select]
