I am not familiar with SPSS, which
I understand to be a statistical package,
but this sounds like
gen count = 0
qui foreach v of var a1-a21 {
replace count = count + (`v' == 5)
}
There is an -egen- function -rcount()-
in -egenmore- on SSC, for which the syntax
would be
egen count = rcount(a1-a21), cond(@ == 5)
but the approach from first principles
gets higher marks from -egen--haters.
