Count the number of obs in a macro variable

[Takatsugu]

Hi,

I am a newbie to SAS and use SAS at work while I have experience in
using R for a while.

I would like to know how to automatically determine the length of
&vars (=5) instead of declaring 10 in the below script....

%let vars = A B C D E;

data _NULL_;
do i = 1 to 10; <---- this value of 10 is what I would like to
automate when I change &vars.
letter = scan(&vars., i, ' ');
put i letter;
if letter = " " then leave;
end;
run;

Any help is appreciated!!!

Thanks.

Taka

how can I automatically count the number of itesm in this macro
variable?

If you were aiming for comp.soft-sys.sas, you missed. This is the
SPSS group.
