st: using macro lists

["Bowser, William (IITA)" <W.Bowser@cgiar.org>]

Dear Statalisters:

I am trying to map sets of variables from different data sets with (possibly) different names, but the same labels and attributes. I have developed the following code thus far and encountered a syntax error that I can't resolve. 

/*=========================================================================*/
//extract sublists of non-attached variables from each country data set //
/*===========================================================================*/


local country Ghana Mali

foreach c of local country {
	 
		qui ds3 if a1 =="`c'", all(missing(X))
*		di "`c'"
*		di "`r(varlist)'"
		local `c'list `r(varlist)'  // this is the variable list for each country //
*		di "``c'list'"
	
}

foreach c of local country {
local `c'lablist

	foreach v of varlist ``c'list' {
		local `c'`v': variable label `v'
		local `c'lablist "``c'lablist' "`c'`v'"" 	//create list of labels in each country //
*		di "`c'"
*		di "`v'`c'"
	
	}

}

/*=============================================================================*/
//Create a list of the intersection of each `country'lablist //
/*=============================================================================*/

***remember to generalize this later ***
local labmatch : list Ghanalablist & Malilablist // this works fine ! //

local n : word count `labmatch'
di "`n'"

foreach c of local country {
	local `c'labmatch :list `c'lablist & labmatch
	local n`c' : word count ``c'labmatch'
}	

// verify matches //
assert `nGhana' == `nMali'
local same : list Ghanalabmatch==Malilabmatch // check to make sure the lists have the same labels //
di "`same'"

I RUN INTO PROBLEMS HERE:

foreach c of local country {
	 
	foreach v of varlist ``c'list' {
	 local inset_`c'`v' : list ``c'`v'' in `labmatch'
	 di `v' if `inset_`c'`v'' == 1
	
	}

}


The above code seems like it should work to me but Stata gives me a syntax error when I run it. Please, any help would be greatly appreciated.

Best,
