分享 Format temporary? permanent?: yukai08008 2013-3-16 22:00; If you do not specify the LIBRARY= option, formats are stored in a default format catalog named Work.Formats. As the libref Work implies, any format that is stored in Work.Formats is a temporary format that exists only for the current SAS session.; 个人分类: 学习笔记|0 个评论
