Hi All:   I would like to propose a solution for a proper use of Global Variables. My assumption came from the fact that most databases are using share memory to construct on the main memory a complete block of their processes and resources. Construction a method for utilizing Global Variable using block concept for common block or sub-block that can be share in any module or main program (i.e. main application and their modules).   The solution implemented in the attached paper can ignite this idea and make you elaborate it to make better use of Python.   Best regards. -------------------------------------------------------------------------------- Ali Abdelaziz Musa Saudi Telecom Company (Technical Advisor) Mob: (+9665)50570742, Hm:(+9661) 405-9425, Off:(+9661) 452-5539 Email: amusa07@yahoo.com
