SAS Micro Analytic Service and SAS Foundation

Although DS2 is supported by both SAS Foundation and SAS Micro Analytic Service, SAS Micro Analytic Service has a lightweight, high-performance engine that does not support either the full SAS language or PROC statements. Therefore, PROC statements cannot be used. However, here is an effective DS2 authoring and testing mechanism: develop your DS2 packages in SAS Foundation using PROC DS2 and publish those packages to SAS Micro Analytic Service after removing the surrounding PROC DS2 syntax.

Here is an example PROC DS2 step that illustrates the above mechanism:

proc ds2;

ds2_options sas;
package myPackage/overwrite=yes;
method copyArray(char(12) in_array[4], in_out char(12) out_array[4]);
    out_array := in_array;
end;
endpackage; 
run;

table _null_;
method init();
   dcl package myPackage p();
   dcl char(12) inarr[4];
   dcl char(12) outarr[4];
   inarr[1] = 'one';
   inarr[2] = 'two';
   inarr[3] = 'three';

   p.copyArray(inarr, outarr);
   put outarr[1]=;
   put outarr[2]=;
   put outarr[3]=;
end;
run;

quit;
