The => proposal is to have the ordering "param_name => > passed_value", just as Oracle has, just as MSSQL has "@param_name = > passed_value", and just as the := proposal would have "param_name := > passed_value". You are right; I am seriously confused. I thought it was value => variable. I was wrong. I now see the Oracle syntax matches the Perl hash assignment syntax. The "=>" operator is helpful in documenting the correspondence between keys and values in hashes, and otherpaired elements in lists. %hash = ( $key => $value ); login( $username => $password ); -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + None of us is going to be here forever. +
