It is not so hard! :-) You can read the file line-by-line and check each line if your keyword, a colon and a number are contained. This can be done by a pattern-matching using a regex. The tricky thing is to find a siutable regex. In your case I would start with: `/Input\s+:\s+(\d+)/;` [download] If you have your line in a variable called $line, you could write `if ($line =~ /Input\s+:\s+(\d+)/) { print $1," is the value of Input"; + }` [download] You can find further reading on Regular expressions/pattern-matching in this collection by planetscape.

What code have you already written? Where do you have problems exactly? How does the code you have fail to do what you want? Please post a self-contained small script and some representative example input so we can reproduce your problems.	[reply]

Smells a lot like homework. For the code you requested, go to `https://homework.{your preferred computer-language}.example.com`. Be aware that that site is rarely on-line (I suspect it's DDOSed by lazy students).	[reply] [d/l]
