Hello Serge. If you're starting with a single file record in a scalar, then 'splice' is irrelevant as it operates only on Perl arrays. You can extract your fields with 'split' if they are comma-separated (or otherwise delimited) or 'unpack' (if they are fixed-length). If the record structure is more complex you may need to use a regex to split it up. Of these, unpack will be the fastest, but you shouldn't be worried about the efficiency of your code until you've written a program and proven it to be unacceptably slow. Until then you should be writing in the way that best describes the structure of your data. It is a useful thing to reduce the run time from 6 hours to 1 hour, but is an expensive waste of effort to improve on a solution with a run time of 60ms to reduce it to 10ms.
