declarative statements are complied time statement then will they execute in the execution phase?
A declarative statement is one that is acted upon during data step compilation.
Examples:
format
length
retain
attrib
by
Their placement within the data step is more or less without effect.
Other statements are executable and will cause action during data step execution.
The set statement somehow falls into both categories; for one, it causes the compiler to read the structure from the dataset(s) and put variables into the PDV; OTOH, it also marks the place within the data step where a read from the dataset(s) happens.
The declarative element with thise statement is the fact that the dataset(s) cannot change during data step execution.
Infiles and outfiles (infile and file statements) can change dynamically during execution.
declarative statements means they will execute in the complie time . they wont execute in execution time. is that correct?
