I did not try this one out, but usually i use the following syntax
(if posse01n to posse30n are not consecutive in your dataset,
 you would have do list these variables like in your count-satement):

vector possed(79).
do repeat x= posse01n to posse30n.
   compute possed(x) = 1.
end repeat.

recode possed1 to possed79 (1=1) (else=0).

hope it helps, Hauke
