I belive it is only possible to open one file and read it into an array.
Stop right there. Why is it that so many bad programmers always read in files into arrays? Who is teaching them that? Which books promote this? Who is giving the courses that do this?

The need to read in a file into an array is uncommon. Often, you go through a file line-by-line, no need to keep more than a single line in memory. Sometimes, you want to entire file in memory - but even then, in most cases, you do not want an array. You'd slurp it into a single string.

Does anybody know how i can have both files open and then use the 'IF x == y' command to write this matching data into a new file.
You can open multiple files by using the open command multiple times. But I haven't the faintest idea how you would use IF x == y (which doesn't look like Perl syntax) to write to a file. I usually use print to write to a file.
