No and yes. If it is genuine new random data then no. If it is fixed length then you can calculate the position and then do a seek to the position. (record length +1) * record number (+2 for cr lf line endings). You can index before hand. For example I have a sort process that reads the file, does a tell for the position of the records, the index is then manipulated and I can read the records in new order by doing a seek. -- Ken Foskey FOSS developer -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
