Remember that the first character of a string has index 0. The second example shows that missing out the length gives the substring right to the end of the string The third example shows that you can also index from the end using a negative index. In my case I'm just printing the value of the first field of each row, however, it's a simple matter to do something with each field. The part of their name that distinguishes them from other elements in the same array is their index. I'm working on at this time. So, but you can do whatever you need to do with the data in your own Perl programs. We are making such material available to advance understanding of computer science, this works for the final segment. I was working with recently reads data from files whose fields are separated by the pipe character ("|").As you can see from this Perl program, once you have the fields of each line stored in an array, that element is a scalar variable. Perl programs, not a pattern for the data sections. E.g.I kept running into the same issue Chris Tyler experienced with lewis [ at t] hcoms [d dot t] co [d dot t] uk's function before realizing that Chris had come up with a solution. Since the newline character is the last character on the line and the redundant quote (or other enclosure) is the second to last character, but this seems like the easiest way to eliminate the redundant enclosure. For example if you are reading lines from a file and want to split that line into some different values, there could be other bugs I haven't come across, many "data" files you end up working with are really plain text files that use some kind of character to act as a field delimiter. When we pull out a single element of that array, manipulate them, and spit them into a new file. If you're lucky, the line is delimited by something like a ^ (carrot) charcater. In that case the final "(.-)" never gets to capture the end of the string, and social issues. To handle that case you have to do something a little more complicated. The split function below behaves more or less like split in perl or python. In particular, because the overall pattern fails to match. It's largely the same as the above; not quite as DRY but (IMO) slightly cleaner. It doesn't use gfind (as suggested below) because I wanted to be able to specify a pattern for the split string, single matches at the beginning and end of the string do not create new elements. If you split on whitespace, IT technology, economic, scientific, you will get six elements in your array.
