Using data files saved in SAS formatsin SAS JMP and the SAS Viewer - Data files saved in various SAS formats from SPSS should work in SAS. There are known problems using SAS files saved in SPSS with the SAS Viewer and SAS JMP 5 - these applications have a different mechanism for reading files which isn’t the same or as stable as the one used in SAS. Filename limitations for data files saved in SAS formats- The following excerpt is from the SAS JMP 5 README: “Double-byte characters should not be used in filenames when writing SAS files [from within JMP]. This is a limitation of the SAS local data provider that is to be corrected in version 9 of SAS”. This holds true for SAS files saved in SPSS.
