Modifying compiler options and phases

If you plan to modify the values for compiler options and compiler phases, use the IGYCOPT syntax format.

The IBM-supplied default values are shown both on the planning worksheets and immediately following each syntax diagram. The syntax diagrams also show the default as explained in How to read the syntax diagrams.

Compiler options and phases, and their defaults, are described in the following information. Review these options and phases and their default values to determine the values that are most suitable for your applications.
