You want require:

-------
data.pl:
$foo = "bar";
$baz = "quux";
-------
program.pl:
require "/path/to/data.pl";
do_something_with($foo,$baz);
-------

require demands that a library file be included if it hasn't already
been included.  The file is included via the do-FILE mechanism, which is
essentially just a variety of "eval".

See 'perldoc -f require' for details.

If you were doing OO perl, you'd just make a module that exported your
constants, say MyApp::Constants, and then
use MyApp::Constants;
and they'd be exported into your namespace.
