[REBOL] Re: big sizes?

Hi Sunanda,
thanks for your explanation. I was thinking of the call scenario before,
but thought there was a better way. Normally info? or size? should do
the job. But i learned that to wait for it to do so could be a little
bit too time consuming. So i think using call is the best solution
available.
Cheers
Thorsten
