Thanks for the update.  Would you be able to share the data file you used
to prepare these examples dmwilliams/Dropbox/random_data.sav ?

     Dear John,
     Sorry it's taken awhile for me to respond with more details about this
     bug. I think the inconsistency between PSPP and SPSS originates in the
     MEANS syntax command (not PSPPIRE like I originally thought),
     specifically the placement/presence of the BY subcommand. I wonder if the
     PSPPIRE dialogs could be left alone if the syntax [sub]commands behind
     them were reversed. Anyway, here's an attachment with screenshots of the
     inconsistent output from both programs. Hope this helps. Congrats on the
     release? of v1.0, btw!
