GDG in UNIX? No Way!

摘要

IBM mainframes in the z/OS environment provide a generational structure often referred to as Generation Data Group (GDG) for file storage to maintain data snapshots of related data.[1] These data resulting from business operations within a servicing organization are not uncommon. This structure can hold TEXT data sets without a problem. However, in the case of a UNIX or Linux platform, a comparable structure is unavailable for use by SAS for storing data as TEXT files. This paper contains a solution to this problem and shows a comparison of what the mainframe GDG offers and the solution offered. A developer or a programmer may find that the solution, TextGDS (SAS macro) is even better than the mainframe GDG structure in certain respects. Although there are both limitations and delimitations when using TextGDS, the tool helps to fill the void with UNIX-SAS.
