Add FLOCK to Edit Perl Script

I need FLOCK (use Fcntl ':flock';)? incorporated into my edit script. This script Adds/Searches/Edits records in a Pipe delimited flat file. The problem: Currently I have 3 admins? adding or editing? info and on a few occasion a new record has caused the script to auto assign 2 of the same numbers which is NOT good. By incorporating FLOCK I hope to eliminate this. Thanks, Aaron ## Deliverables I need FLOCK (use Fcntl ':flock';) incorporated into my edit script.
