Dont. Just don't. Use good design in your program instead. Good design does not require having global variables. > > so it is in the @EXPORT_OK and even in the @EXPORT. So far so good, i > thought! Export functions, not variables. Don't try to share variables between files, or even between functions and you will save yourself a lot of grief. Instead, learn how to pass arguments to functions, and how to use references to allow functions to access arrays, hashes, and objects. perldoc perlref perldoc perlsub perldoc perlmod perldoc perlobj > > but nothing happens when i run the caller-program... > > i tried also defining with 'my ..' , or without 'use strict' ... > > somebody has the clue? > > thanx > -ralf If you explain what you are trying to accomplish, we can probably help you to use modules appropriately to accomplish the task. I would suggest that until you are ready to take on serious object-oriented design, you should focus on uisng subroutines well and passing arguments to and returning values from subroutines. Don't try to get around scoping restrictions. Work with them instead. The discipline they impose is very healthy, and will make your programs much more dependable.
