|XP is just a number|
Thanks for this. Well I can see:
If omitted, $user defaults to the ISC_USER environment variable (or, failing that, the DBI-standard DBI_USER environment variable). Similarly, $password defaults to ISC_PASSWORD (or DBI_PASS). If $dbname is blank, that is, "dbi:Firebird:dbname=", the environment variable ISC_DATABASE is substituted.
For using with the connect statement, but I don't see anything for using with install and it's cpan -i DBD::Firebird which is falling over not the connect statement.
But it's true that cpan -i DBD::InterBase asks a lot of questions, the answers to which it presumably put into environment vars, and you might expect DBD::Firebird to need the same info. Am I missing something?
Thanks again for your help.
