CGOPTIMIZE=0 | 1 | 2 | 3

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.
