Example 3: Using the CMACVAR= Option with MP CONNECT

Purpose

The following example enables you to remotely submit processing in a server session and allows the client session to immediately continue processing, and then retrieve and merge the results upon completion of that process.

The following program submits a PROC SORT and a PROC PRINT statement to be executed asynchronously in a server session. This server process is tested for completion by using the macro variable DONE.

Program

rsubmit cwait=no cmacvar=done;
   proc sort data=permdata.standard(keep=fname
      lname major tgpa gender)
      out=honor_graduates(where=(tgpa>3.5));
      by gender;
   run;

   title 'Male and Female Honor Graduates';
   proc print;
      by gender;
   run;
endrsubmit;

%macro get_results_when_complete;
   %if &done=0 %then %do;
     %put Remote submit complete,
        issuing "rget" to get the results.;
     rget;
   %end;
   %else %do;
     %put Remote submit not complete.;
     %put Issue:
        "%nrstr(%%)get_results_when_complete" 
        later.;
   %end;
%mend;
%get_results_when_complete;  

/* continue with client session processing */
/* issue again if RSUBMIT not complete */

%get_results_when_complete;
