You should use the SPSS i/o dll, which provides functions to read and write SPSS data files rather than trying to work with the rather complex file format directly. Besides being much easier than deciphering the file directly, it insulates you from changes to that format as the file evolves.
You can download this dll and the documentation from SPSS Developer Central (www.spss.com/devcentral) in the Downloads section. Look for SPSS Developer's Kit, currently on page 8 of the Downloads list.

Subject: [SPSSX-L] SPSS Data file structure
Hello
I am planning to develop a program in which I would like to directly access
(read and write) SPSS data files. Can anyone tell me where I can find
technical information concerning the structure of an SPSS data file
(particularly for versions 13 and later).
Thanks
