I think the example below may do the job Tiago wants to do, though
others may have a better solution for Tiago.

** Begin example ****

* Create 10 scalars
forv i=1/10 {
	scalar myscal`i'=`i'+3
	di "scalar =", myscal`i'
}

* Or if you will
scalar list

* Now let's sum them
local i=1
scalar mysum=0
while `i'<=10 {
	scalar mysum= mysum + myscal`i'
	local i=`i'+1
}
di mysum

** End example *****

Hope this helps
