How to access variables from another module

[helpcomm]

Hi,

I am new to perl and i want to debug a perl program.

I have the following statement:
$dbh=DBI->connect("DBI:mysql:$DBNAME",$DBUSER,$DBPASS)

And i want to display the content of DBI:mysql:$DBNAME so that i know what is the name of the database.

i did : print DBI:mysql:$DBNAME;

But it does not work!

Thank you

Am I missing something?

print $DBNAME;

Just to clear things a bit, DBI:mysql:$DBNAME is not variable $DBNAME in the module DBI:mysql. This syntax is specific to DBI and it simply encodes three things in one parameter.

If you really had a DBI::mysql module (notice the double colon), and a $DBNAME variable in it, you'd spell it like this:
$DBI::mysql::DBNAME
Notice the sigil before the package name and double colons as separators.
