Thank you. You say "tell the second data step to use the output of the first data step as the input instead of going back to the source data.". How exactly would I do that?
This step will create a dataset called STEP1 from a dataset call OLD.

set old;
run;
If you then want to use that data and make more calculations then use as the data to be read. So you could create STEP2 from STEP1 with a data step like this.
data step2;
set step1;
run;
