%syslput not working in rsubmit SAS

Question

----------------------Implementing use of rsubmit & accessing values passed to it----------------------------

I am trying to write a code which will create different remote session, also it'll pass data set values to particular rsubmit blocks with the help of macros. We know that simple macro variable values cannot be sent to rsubmit statements because rsubmit creates new session. Thats why I used %syslput statement. But its not working, please tell me how can I pass data set values to the rsubmit statements using %syslput.

    options sascmd='!sascmd -nosyntaxcheck'  autosignon=yes sysrputsync mprint symbolgen;
    data data;
    input num@@;
    datalines;
    1 2 3
    ;
    run;

    %macro startTask(n);
        %syslput number=&n;
        rsubmit Task&n wait=no;
            %put Output from Task&number;
            %put Value of Number:=&number;
        endrsubmit;
    %mend;

    %macro finishTask;
        waitfor _ALL_ Task1 Task2 Task3;
        signoff Task1;
        signoff Task2;
        signoff Task3;
    %mend;

    data _NULL_;
    set data end=last;
    call execute('%nrstr(%startTask('||strip(num)||'))');
    run;

   %finishTask

Updated macro code:

%macro startTask(n); 
signon Task&n; 
%syslput number=&n /remote=Task&n;
rsubmit Task&n wait=no; 
%put Output from Task&number; 
%put Value of Number:=&number; 
endrsubmit; 
%mend;

Answer 1

When you use a %syslput statement you need to specify which remote session you want it to target, e.g.

%syslput remote_var = value /remote=remote_session_name;

If you don't specify a session, I think SAS tries to use the one you last remote submitted code to. But because you are using autosignon, you are trying to do your %syslput before you've even signed on to the remote sessions generated by the rsubmit.

Try signing onto your sessions first before using %syslput to synchronise your macro variables and see if that helps. E.g.

%let number = 1;
option autosignon = no;
signon task1;
%syslput number_remote = &number /remote = task1;

That should create a macro variable called number_remote in the session task1 with the value 1.

Answer 2

Your macro variable needs to be within a macro in the rsubmit if you wanna use the remote macro variable. It's easier if you just wrap everything in a macro. Try this:

%macro startTask(n); 
signon Task&n; 
%syslput number=&n /remote=Task&n;
rsubmit Task&n wait=no; 
%macro test();
%put Output from Task&number; 
%put Value of Number:=&number; 
%mend test;
%test;
endrsubmit; 
%mend;
