Re: st: Defining upper limit of loop

[Nabin Kafle <nkafle89@gmail.com>]

I want to loop a cycle number of times indicated by a number in a variable name.
For example:
X Y Z
1 2 1
2 3 4
3 2 2
3 2 2
4 2 2
. . . .

gen sum=X
forvalues i=1/"Z" {
replace sum=X+X[_n+`i']
}

What would be other way to do such if it is not possible by -forvalues- command.
