QUESTIONS ON SCRIPT EXAMPLE 4—PERL: DBI DATABASE INTERFACE SCRIPT (p. 592)
  1. The script does not report a problem if neither the "load" nor "query" options are specified. Add code to detect this condition and print out a usage message.
  2. Change the script so that if the no -qid option is given but all other query options are present, the database query is run for all BLAST query sequences.
