SPSS Code Fragment
An example in SPSS macro programming

define !es (nobs=!TOKENS(1)
/group=!TOKEN(1)
/vnames=!CMDEND) 
compute nobreak = 1.
/* looping through all the variables */

!DO !vname !IN (!vnames) 
!LET !f=!CONCAT("f", !vname)
!LET !g=!CONCAT("g", !vname)
!LET !s=!CONCAT("s", !vname)
glm
  !vname  BY nobreak
  /METHOD = SSTYPE(3)
  /INTERCEPT = INCLUDE
  /SAVE  = PRED (!f ) 
	     SEPRED (!s)
  /CRITERIA = ALPHA(.05)
  /DESIGN = nobreak .
glm
  !vname  BY !group
  /METHOD = SSTYPE(3)
  /INTERCEPT = INCLUDE
  /SAVE  = PRED (!g)
  /CRITERIA = ALPHA(.05)
  /DESIGN = campus .
  compute !vname = (!g - !f)/(!s*sqrt(!nobs)).
  execute.
!DOEND 
means
tables =!vnames  by !group
/cells mean .
!enddefine.
*example: 
!es nobs=30  group=campus vnames=q2 q3 q4 q10.
