Gen~ clear data

Hello comrades!

maybe someone can enlighten me:

How I can delete a data object (in gen) (without using "reset", which affects all in the Gen patch : p ) without using codebox Gen. Y (for> poke data, "0") as this creates an interruption (cpu-spike? or some click) in the audio stream.

I tried using phasor> @ index phase alone in the clearing process but neither worked.

I need some method, not noisy or expensive process to delete a data buffer (dim 5.67 million) in seconds.

thanks
