libname data "X:\blabla \data\";

PROC IMPORT OUT= WORK.myfile

            DATAFILE= "X:\blabla \data\Stata datasets\data1"

            DBMS=STATA REPLACE;

RUN;

libname data "X:\blabla \data\";

PROC IMPORT OUT= WORK.myfile

            DATAFILE= "X:\blabla \data\Stata datasets\data1"

You can find the documentation of proc import in Base SAS(R) 9.4 Procedures Guide, Second Edition. If you don't like reading docs simple execute the proc and see what SAS has to say Smiley Wink

I don't know about STATA files but in many cases you can use a FILENAME statement to associate multiple files and read them.

Question: You have one output file and two input, are you wanting to have the data from the two STATA files combined into a single SAS data set?

You want to combine the variable from the new file with the variable from the old file then you want to do some type of merge.

If you have a simple file with a unique id variable then a data step merge will do the trick.

libname data "X:\blabla \data\";

PROC IMPORT OUT= WORK.myfile

            DATAFILE= "X:\blabla \data\Stata datasets\data1"

            DBMS=STATA REPLACE;

RUN;

PROC IMPORT OUT= WORK.myfile2

            DATAFILE= "X:\blabla \data\Stata datasets\data2"

            DBMS=STATA REPLACE;

RUN;


data want;

   merge myfile myfile2;

   by ID ;

run;
