Nick,
Your explanation is very helpful. I will try it again.

First, what you are writing is called a macro in some other
languages, but not in Stata. Keep the terminology for
some alternative software you may have encountered.
You can assign
. local vars "var1 var2 var3 var4 var5 var6 var7 var8 var9 var10 var11
var12 ... varn";
and that is legal. At that point the local is just a string, and its
contents
are under your control. But Stata cannot make sense of this when you
want to interpret it as a varlist. It will choke at the "...".
Alternatively, my guess is that this is _not_ what you wrote, in which
case you are just confusing the issue by posting a mix of real code
and
pseudocode.
I sense various other typos and unnecessary complexities in the code.
The one that is halting your code is probably that after substitution
the line
sum `v1' if `samp1' [aw=`v1']
will be
sum <all your variables> if if prown3 == 0 [aw=<all your variables>]
This is most unlikely to be what you want, but the "if if" is what
Stata is choking on, as it is trying to tell you.
A more general comment is that you are trying to run when walking
will do the job very well. Setting up a loop is not needed as
-summarize- does that for you.
Your code seems to boil down to
-------------------------------------
set mem 67m
use "C:\newset.dta"
su <varlist> if prown3 == 0
-------------------------------------
in which you need to plug your variable names into <varlist>,
except that I cannot work out how you want to apply weights.
