Conditional Compilation Directives

The conditional compilation directive statements allow you to conditionally include or exclude sections of source code from the compile.

• Condition-names can be added or removed from a list of currently defined conditions using the defining condition directives /DEFINE and /UNDEFINE.
• Condition expressions DEFINED(condition-name) and NOT DEFINED(condition-name) are used within testing condition /IF groups.
• Testing condition directives, /IF, /ELSEIF, /ELSE and /ENDIF, control which source lines are to be read by the compiler.
• The /EOF directive tells the compiler to ignore the rest of the source lines in the current source member.
