Answer / 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.

There are hell lot of differences between a Compiler and an Interpreter.But the two which I would take to prove that SAS actually COMPILES and is not Interpreted are:
1)A Compiler takes entire program as input while an interpreter takes single instruction as input.
SAS is a compiler as it does not read and execute one statement at a time. It will either wait for a RUN, QUIT, next DATA or PROC statement before executing its statements.
2)In compiler errors are displayed after entire program is checked.While in interpreter it is displayed for every instruction interpreted.
In SAS all errors are displayed after checking the particular data/proc step.

Answer / ganesh
My answer is interpret. Why because compile means it checks
all the errors at onetime and gives the output. but coming
to the interpret it going check by errors line by line and
observation by observation and inbetween any errors occour
i stops the process for the next step.

Answer / koduri
sorry vsrao, its a interpret.
compile means it will execute once and display all errors,
interpret means it's check each line by line . suppose on
the middle of the program any error it's stop.(ex: _error_=1
always ie reasion)
