Dynamic Search with FIND/INDEX

lyton80 — Sat, 01 Feb 2014 21:16:14 GMT

With this code I intend to do a dynamic search in Name field and enter the search term (a macrovariable sn_term&i) if found into NewN. I am having issues with the outputing the results; the last search term tend to overwrite the previous ones. Thanks in advance.

%macro mstrial;

data newlbname;

set SmplEHM;

%let i=1;

%Do %until(&i>&p);

select;

when ((find(Name,"&&sn_term&i"))GE 1)

%let Mvname= &&sn_term&i;

NewN = strip(symget('Mvname'));

otherwise ;

end;

%Let i=%eval(&i+1);

%end;

run;

%mend ;

Do not use SYMGET() as it will run after all of the macro code has finished so it will always retrieve the last value assigned to MVNAME.

Also you seem to be generating multiple SELECT statements instead of multiple WHEN statements within a single SELECT statement.

You probably want something like this.

%macro mstrial ;
