Dear Douglas, thanks for the reply and the new bug descriptions regarding t-test groups and the regression command.
I opened a bug in the bug database regarding the regression syntax: http://savannah.gnu.org/bugs/?45667 The spss v23 syntax description ftp://public.dhe.ibm.com/software/analytics/spss/documentation/statistics/23.0/en/client/Manuals/IBM_SPSS_Statistics_Command_Syntax_Reference.pdf says that the groups command should separate the values with comma, but I guess you produced the syntax via the spss GUI, right?
