Hi, I need to create a 512 bytes buffer in memory, in which I can write date like in a stream ('output). Then, when the buffer is full, I have to write it to a file, for example with Buffer'Output, or once byte each time, but the raw content, no headers or something, just the raw 512 bytes. Where should I begin to look at? Something to do with storage pools? Thanks -- (:==================:) �lvaro Iradier airadier@able.es (+34)660133259 (:==================:)
