A macro variable with a list of parent datasets

[PhilC]

Suggesting a possible name, "_CLIENTparentDATASETlist", which is, as described, the list of dataset's connected as parents to the current program node. For example:

%LET _CLIENTTASKLABEL='Program3';

%LET _CLIENTPROJECTPATH='';

%LET _CLIENTPROJECTNAME='';

%LET _CLIENTparentDATASETlist=SASHELP.CARS SASHELP.FLAGS SASHELP.IRIS;

%LET _SASPROGRAMFILE=;

And the use of the macro variable is for what purpose? How will you use the value?

[PhilC]

E.g.'s:

data concat;
  set &_CLIENTparentDATASETlist;
run;

OR

%MACRO doForEach( datasets);
  %let dataset=%scan(&datasets,1); %let i=1;
  %do while ("%dataset" %ne"");
     proc print data=&dataset;run;
      %let I=%eval(&I + 1);    
      %let dataset=%scan(&datasets,&i); 
   %end;
%MEND;
%doForEach(&_CLIENTparentDATASETlist);

Since we are talking about Enterprise Guide, the datasets are already explicitly written in the code(s) by EG itself.

Your idea would only make sense if you wanted to control the input datasets by making connections in the process flow, but EG does it the other way round by creating connections in the process flow depending on the dataset names in the tasks themselves.

BTW, just a simple list of dataset names would never be sufficient. Tasks often deal with several datasets at once, where each dataset plays a different role, so you would also need to know which dataset is which.

Bottom line: not feasible.
