3-5 Optimizing Your Code
3.2.2 Creating an Optimization Information File ( − on n Option)
When you invoke the optimizer with the − o3 option, you can use the − on option
to create an optimization information file that you can read. The number
following the
− on denotes the level (0, 1, or 2). The resulting file has an .nfo
extension. Use Table 3 − 3 to select the appropriate level to append to the − on
option.

Do not want to produce an information file, but you used the − on1
or − on2 option in a command file or an environment variable. The
− on0 option restores the default behavior of the optimizer.
