CIFDEF, CIFNDEF, and CENDIF

The CIFDEF, CIFNDEF, and CENDIF commands generate the compiler directives

#ifdef, #ifndef, and #endif, respectively, for C output.

identifier_name

is the name of the identifier affected by the command.

The DDL compiler does not store identifier-name in the dictionary.

Each CIFNDEF or CIFDEF command have a corresponding CENDIF command.

After closing a C source code file, the DDL compiler checks whether the CIFNDEF and

CIFDEF commands match the CENDIF commands. If not, the DDL compiler issues a

warning.

Before generating C output for CENDIF command, the DDL compiler checks for the

corresponding CIFDEF or CIFNDEF command. If the DDL compiler does not find the

corresponding command, then it issues a warning and does not produce output for the

CENDIF command.

You can nest CIFNDEF and CIFDEF commands

{ CIFNDEF } identifier_name

{ CIFDEF }

CENDIF
