Syntax
Syntax Description
- 0
-
specifies not to perform
optimization.
- 1
-
specifies to perform
stage 1 optimization. Stage 1 optimization removes redundant instructions,
missing value checks, and repetitive computations for array subscriptions;
detects patterns of instructions and replaces them with more efficient
sequences.
- 2
-
specifies to perform
stage 2 optimization. Stage 2 performs optimizations that pertain
to the SAS register.
Interaction:Stage 2 optimization for a large DATA step program
can result in a significant increase in compilation time and thus
overall execution time.
- 3
-
specifies to perform
full optimization, which is a combination of stages 1 and 2. This
is the default value.
