The Year 2000 date change issue affects all organizations that use computer systems in the course of their business. Especially federal systems, because of their dependence on many older systems which have been successfully operating with only minor modifications during the past 10-30 years. This issue applies to all programming languages and operating systems as well as exec routines, macros, job control language, custom spreadsheets, personal database applications, ad-hoc queries and report requests.

Today, data is shared among many organizations on a daily basis.
