You say 'writing $PDL::BIGPDL=1 doesn't do it'. What is the code? What error message do you get? Could it be that you typed, say, $PDL::BigPDL=1 (not all-caps) instead?

Note that $name->$PDL::BIGPDL tries to call the method whose name is stored in $PDL::BIGPDL on the object $name, which is almost certainly not what you want; and $name = $PDL::BIGPDL = 1 will indeed set $PDL::BIGPDL to 1, but will then put that same 1 into $name, which is probably not what you want. Qualifying $BIGPDL with PDL:: already specifies the package; you don't need the help of an object to do this.
