Useful Values

ObjectARX provides the following preprocessor definitions for use with legacy global functions:

#define TRUE 1 
#define FALSE 0 
#define EOS'\0' // String termination character 

The PAUSE symbol, a string that contains a single backslash, is defined for the acedCommandS()/acedCommandC() and acedCmdS()/acedCmdC() functions, as follows:

#define PAUSE "\\" // Pause in command argument list 

Note: The ObjectARX library doesn't define the values GOOD and BAD, which appear as return values in the code samples throughout this guide (especially in error-handling code). You can define them if you want, or substitute a convention that you prefer.
