Hashtable Question

sasmaverick — Thu, 01 Oct 2015 07:49:17 GMT

I have the following code which replaces country codes from a country code dataset.

%macro replace(file,country);
data &file.;
if _n_=1 then do;
if 0 then set country_codes;
declare hash h1 (dataset:'country_codes');
rc=h1.definekey('iso_code');
rc=h1.definedata('country');
rc=h1.definedone();
end;
call missing (of _all_);
set &file.;
rc=h1.find(key:&country.);
drop rc ISO_Code;
if missing(Country) then Country=&country.;
Country=upcase(Country);
run;
%mend replace;
%replace(contacts_all,country);

The above code replaces all instances of 'BR' to Brazil but in the final output, one observation of BR still remains. What could be causing this? Thank you.

It is difficult to visualize your probelm.. The answer will be quick if you make us to see your problem in terms of some input data set(even mock will do) and the desired output data set.

I would check to see if that value of "BR" is actually " BR" with a not very noticeable leading space.
