I just saved a SAS file from SPSS on the PC, selecting the version for Unix that has the file extension .ssd01. After uploading to our Unix system and running some SAS analyses I have discovered that the missing values, which are clearly defined in the SPSS file in the Data Editor, are not missing values in Unix SAS 8.2. The missing values are -1 for all variables in the SPSS file and they show up as the Minimum value in proc means in SAS (ie, as VALID data). In other words, the SAS file that SPSS made did NOT flag the missing values.

I just wanted to alert people to this and wonder if anyone else has come across this. I'm going to try a file for PC SAS tomorrow and see if the missing values are flagged there.
