I want the local macro to take the value of var1 for the same row for which
var2 takes a specific value, say 5 or "Texas". I know a priori that var2
will take that value only once, so macroname will end up containing only one
number coming from var1.
Example, my need is to find a way to do something like passing the GDP of
Texas to a local macro. Inside var1 I have all GDPs for each state and
inside var2 I have the name of all states. Something like this
. local macroname = var1 if var2=="Texas"
where I know a priori that Texas will appear only once in var2.
If I knew a priori that Texas where in the, say, 22nd observation, then I
would just write
. local macroname = var1[22]
and be done with it. But in the ado I am programming "Texas" can appear at
any place. Sorting would not help.

While writing for you what I meant with my work-around I understood why it
does not work. I am not sure that explaining my mistake would help. I think
it would just generate more confusion, so I omit it.

. forv i=1/7 {
  2. local cty = var1[`i']
  3. local gdp`cty' = var2[`i']
  4. }
