The following table lists and describes the preprocessor options for HCS08 Compiler.

Table 1. Tool Settings - HCS08 Compiler > Preprocessor Option
Option	Description
Define preprocessor macros (-D)	Define, delete, or rearrange preprocessor macros. You can specify multiple macros and change the order in which the IDE uses the macros. Define preprocessor macros and optionally assign their values. This setting is equivalent to specifying the `-D` `name[=value]` command-line option. To assign a value, use the equal sign (=) with no white space. For example, this syntax defines a preprocessor value named `EXTENDED_FEATURE` and assigns `ON` as its value: `EXTENDED_FEATURE=ON` Note: If you do not assign a value to the macro, the shell assigns a default value of 1.

The following table lists and describes the toolbar buttons that help work with preprocessor macro definitions.
