If the Illegal Pragmas option is on, the compiler displays a warning when it encounters an illegal pragma. For example, these pragma statements generate warnings:

#pragma near_data off    // WARNING: near_data is not a pragma.
#pragma far_data select    // WARNING: select is not defined
#pragma far_data on        // OK

The Illegal Pragmas option corresponds to the pragma warn_illpragma, described at "warn_illpragma." To check whether this option is on, use __option (warn_illpragma).See "Checking Options" for information on how to use this directive.
