Answer Posted / senthilkumar govindarajan
A typical SAS program could contain DATA steps, PROC steps
and macros. Macros are preprocessed. DATA steps are just in
time compiled. PROC steps are interpreted in the oreder
they appear in program. So when we submit a SAS program
consisting of all these three componenets, the macro is
compiled and executed first. If a DATA step is encountered,
then it is compiled and executed. Note that the DATA step
will not be executed if there is an error in the
compilation. If a PROC step is encountered, it is
interpreted and executed line by line. However i am not
certain on this PROC step behaviour.
