Would like to share following working code.

Objective: Read the third field of Central Data pool file then print it to timing file.

Central Data pool file looks like this:
###Prashant,Patel,89 Dayton Dr

extern "C" int rhobot_script(PLAYER_INFO* s_info)

// Declare Variables
CLoadString myMsg = "";

myMsg = VARDATA(3);
SCRIPT_MESSAGE ("MyGroup", myMsg);

To see the message into Timing file, go to summary report then click under "#Thinned Messages".
