     I am using 64bit PSPP 0.7.9 on Windows 7 Professional and am running into

     to open fine in PSPP. Once opened, however, pretty much anything done to it
     will cause the program to hang.  This happens with both the 32 bit and 64
     bit versions on two different computers, both with Windows 7.  Saving it to
     another filename caused it to crunch for 30 minutes or so and then it just
     finally stopped and closed the file with no message. The file contains 
     30,000 records and about 5,000 variables (I know, it's really huge).  I am
     able to work with it in SPSS with no problem and was hoping to migrate some
     of the work over to PSPP. Is this filesize beyond it's scope?

No.  PSPP should handle files of any size.

However, there was a bug in 0.7.9 (which affected only Windows versions) which
was fixed very recently. So if you are using one of Harry's prebuilt binaries,
then you should make sure it was one published on or after 15 June 2012.
If you've done that and still experience crashes, then please let us know.

Clearly with such a large file, it will take time to process - so be patient!  
Some speed improvement is likely if you set your WORKSPACE to a larger value - 
depending upon the amount of memory that you have available.

And of course, for applications where reliability is paramount, Windows is
never going to come up with the goods.  So I would consider switching to
GNU/Linux if you need a really robust toolset.
