One column of what?
Fourteen rows of what?
Split what in half?
Are you trying to rearrange a table?
If so how should the items in the table be rearranged?
Your Possible Table Results ----- ----- ----- A A B A H B C D B I C E F C J D G H D K E I J E L F K L F M G M N G N H I J K L M N
Here's some perl code that prints out simple tables from an array.
use strict; use warnings; my @stuff = 1..14; # Print 14 rows in one column. print "\n\n14 Rows\n"; print join "\n", @stuff; # Print 7 rows two columns print "\n\n7 Rows One Way\n"; print map { "$stuff[2*$_]\t$stuff[2*$_+1]\n" } 0..$#stuff/2; print "\n\n7 Rows Another Way\n"; print map { "$stuff[$_]\t$stuff[$#stuff/2+$_+1]\n" } 0..$#stuff/2;
You won't be able to write a program in any language unless you can clearly describe what you want to do in any suitable human language (such as English).
Start your program by writing comments:
# Open a text file # Read the file # Print file contents out like this # LINE_1 LINE_2 # LINE_3 LINE_4
Then start filling in the Perl between the comments.
If you get stuck, try posting a clear question with your code so far, and you'll have much better luck.
Happy hacking. When I was starting out, I found How to RTFM to be a very useful post. Note that perldoc.com is long gone, so use http://perldoc.perl.org to find perldoc on the web.
