----- Messaggio originale -----
[...] So, Diego's code could be rewritten as

local array1 a1 b1 c1
local array2 a2 b2 c2
local n : word count `array1'
forval i = 1/`n' {
    local var1 : word ‘i' of ‘array1'
    local var2 : word ‘i' of ‘array2'
    ttest `var1' = `var2'
}

Thank you Nick for your suggestions and corrections (really appreciated).
Unfortunately the code still does seem to work: 

. 
. local array1 bnp1 tnt1 ef2
. local array2 bnp2 tnt2 ef2
. 
. local n : word count `array1'
. forval i = 1/`n' {
  2.     local var1 : word ‘i' of ‘array1'
  3.     local var2 : word ‘i' of ‘array2'
  4.     ttest `var1' = `var2'
  5. }
invalid syntax
r(198);

where bnp? tnt? and ef? are three real variables of my dataset. 

Any ideas ? 

Diego
