Visual FoxPro Programming Standards and Guidelines. Purpose of Document The purpose of this document is to consolidate and clearly define the standards and guidelines that have been approved and are currently being practiced by the development staff at our company. These guidelines are a living list of items. All applications created during this timeframe are expected to follow these guidelines unless technically prohibited, until such time that a revision of these guidelines is released. It is not the intention of the development teams to grandfather these practices back to previously developed applications, nor projects assumed from clients that were developed by another company. Henceforth it will be necessary to indicate the version of standards followed in the documentation and code headers of the application being created.
