Compile Error Help?

Pardon my newbie (to TI compiler) question, but can anyone give me some guidance on why the compiler doesn't like this:

 

 

 

#define MAX_PACKET 1024; 

unsigned char data[MAX_PACKET];

and gives the following error message:

Thx

    You have a semicolon after the 1024.

    The preprocessor blindly replaces any occurrence of "MAX_PACKET" with the rest of the line, thus when expanded you will have

      unsigned char data[1024;];

    You can use the -ppo compiler option to preprocess the code without compiling it, and look at the resulting .pp file to see how it expanded.

    It is also recommended to do

      #define MAX_PACKET (1024)

    to avoid accidental concatenation of the "1024" with its surroundings.
