Hi People,

I need to write down a command that has too many variables but I do not want to write down all of the variables that I use. Suppose that I have var1, var2, Var12 and I want to have a command like:

replace Dot=Quick if var==0 & var2==0 & ....& var12==0.
Is there a way to make a shortage of that? I tried possible different varlist definitions like:

replace Dot=Quick if var*=0

but they do not seem to work.
An additional question is that I tried to write a the commands within an if but Stata is not doing anything. So I wrote:

if var1==0 & var2==0 {
    replace Dot=Quick

and it is not doing any changes whasoever. Whereas if I write it

replace Dot=Quick if var1==0 & var2==0 

it does the changes. Is there a problem with my syntax of the if command?

Thanks in advance!
