Recursive data step reference

[ Edited ]

HI all 

 

I have a situation where I have to read from sas dataset A and create dataset B and next time in the do loop I have to read it from Dataset B and so on ! How can I achieve this?

 

Thanks for all the help!

Hi @SASSLICK001,

 

Can you please provide more details on your question, e.g., sample data (in the form of a data step) together with the intended result and existing SAS code (or pseudocode) of the algorithm you have in mind? For example, is the DO loop a macro %DO loop?

It is also quite likely if your additional datasteps are only calculating new variables and such that they could all be done in one datastep.

Maybe proc datasets command AGE could be useful here

 

proc datasets lib=myLib nolist;

age B A OLD_A OLDER_A;

run;
