is there any method to call vars directly?
I believe not. From Delphi help:
"Global variables declared in a shared library cannot be imported by a Delphi application.
A library can be used by several applications at once, but each application has a copy of the library in its own process space with its own set of global variables. For multiple libraries--or multiple instances of a library--to share memory, they must use memory-mapped files. Refer to the your system documentation for further information."

The history of software is strewn with defects caused by the use of "global" shared variables. That's why encapsulation is such a valuable concept.
