Hi Glenys

GL> I want to conduct One-way ANOVA's of a few DV's with a very large number of
GL> IV's (grouping factors).

GL> Is it possible to write syntax that creates a routine that will repeat the
GL> instructions for each of the IV's? I have searched this site and others for
GL> macros that might do this, but to no avail.

Is this what you want? (make sure that "C:\Temp\" folder exists).

MACRO definition.
DEFINE ALLANOVA (y=!ENCLOSED("(",")")/ x=!ENCLOSED("(",")")).
DO IF $CASENUM=1.
!DO !i  !IN (!y).
!DO !j  !IN (!x).
WRITE OUTFILE "C:\Temp\AllANOVAS.sps"
 /"ONEWAY"
 /!QUOTE(!i) " BY " !QUOTE(!j)
 /" /STATISTICS DESCRIPTIVES HOMOGENEITY"
 /" /POSTHOC = SNK TUKEY ALPHA(.05).".
* I have selected some descriptives&statistics,
* modify them if needed, but be careful with the / and " .
!DOEND.
!DOEND.
END IF.
EXECUTE.
INCLUDE FILE="C:\Temp\AllANOVAS.sps".
!ENDDEFINE.

* MACRO call *.
ALLANOVA y=(list of depvar) x=(list of IV).

"It is unwise to use a statistical procedure whose use one does
not understand. SPSS syntax guide cannot supply this knowledge, and it
is certainly no substitute for the basic understanding of statistics
and statistical thinking that is essential for the wise choice of
methods and the correct interpretation of their results".
