Email from Douglas Bonett:

There seems to be more serious discrepancies between SPSS and PSPP syntax for
linear regression. For a simple linear model SPSS produces

REGRESSION
  /MISSING LISTWISE
  /STATISTICS COEFF OUTS CI(95) R ANOVA
  /CRITERIA=PIN(.05) POUT(.10)
  /NOORIGIN
  /DEPENDENT y
  /METHOD=ENTER x.

while PSSS gives

REGRESSION
    /VARIABLES= x
    /DEPENDENT=     y
    /STATISTICS=COEFF CI R ANOVA.

SPSS V22 does not accept the PSPP regression syntax. 

==============

I tested this in a more or less current branch. This syntax works on pspp:

REGRESSION VARIABLES= a
    /DEPENDENT=     b
    /STATISTICS=COEFF CI R ANOVA.

and also this syntax works

REGRESSION 
    /VARIABLES= a
    /DEPENDENT=     b
    /STATISTICS=COEFF CI R ANOVA.

and produces the regression result. However the SPSS manual for version 23 

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 METHOD parameter is required.
