Hello,

Thank you for your reply, but I specify my problem:
- Variables in the questionnaire
  Var1 ##   
  Var2 ##
  Var3 ##
  Var4 ##
  Mean4 ##.##

- In CHECK file (or ANALYSIS)
   mean4
   mean4 = (var1+var2+var3+var4)/4
   end
 
- But sometimes, var2, for example, can fail (blank):
  in this case, "mean4" is the sum (Var1 to var4) divided by 3!

- My question is, how to count automatically (CHECK or ANALYSIS)
   the number of variables (var1 to var4) not missing?

Thank you for your help.

B. BRANGER, Nantes, France

Dear Bernard,

What do you think about count if [logical statement].

For example: count if km=. will return the number of km that are missing in
the data set. Additionally you can list such list id if km=.
Please let me know if this helps.
