I have what is probably a simple question, but I haven't had much luck solving it myself, so I thought I would throw it out to the group. I have several text files where I have two columns of data delimited by a tab. I would like to combine these files into a single file with many tab delimited columns. The approach I am taking involves creating a hash that contains anonymous references to other lists, reading each of the files, splitting each line on the tab, and appending the resulting list to one of the anonymous lists stored in the hash. Is there a module to perform this operation or perhaps a more elegant way to do this? -- Richard L.
