You will get good answers for CDF for sure...

PROC in PROCs are not possible also nested DATA-steps or nested PROCs with
DATA steps are impossible in SAS.

DATA step1;
  statement1;
  DATA step2;
    statement2;
  RUN;
RUN;

is the same as:

DATA step1;
  statement1;
RUN;

DATA step2;
  statement2;
RUN;
RUN;

Because also a new DATA or PROC statement ends the preceeding one, like
RUN; and the extra RUN; at the end does nothing.
