Is there a way to clear the log?

Id like to make a simple addition to the simple mob grinder. I have added variables for mobs killed, mobs looted, and times ive died and ran back sucessfully.



Id like to throw those variables in the log, which i have done, i would just like to clear the log each time before it outputs the numbers there.



I was hoping one of you guys knows how to do something like : Log(clear); or something like that... i havent been able to figure it out.



Thanks for the help!
