Chris, blocking does take place at multiple levels: first at the transport layer where there is the "data transfer" blocksize and then as input into a translator. Some translators) at last in the olden days - required the I/O to be in a specific block of data: some at 80 characters, some at 256 characters - while others could elegantly handle the interchange as a data string - which is the underlying design concept of the X12 standards. The X12 standards to not have any concept of a record or block - it is a string of data with delimiters and tags to enable parsing.

I have always [1] considered the blocking of data to be a part of the transport mechanism, and therefore agnostic towards the specifications of the actual data which was being moved. Regards Chris [1] Since it is nearly twenty years since I last encountered blocked data this is not a fresh opinion. -- Chris Johnson mobile:+44 (0)7785 302122 Fax: +44 (0)870 0519 818 EDI website http://www.edimatrix.co.uk EDIMatrix Ltd work: 0845 126 0680 or +44 20 8778 1402 Registered in UK no. 2777624 Reg.Office: 34 Sydenham Rd, London SE26 5QF [Non-text portions of this message have been removed] ------------------------------------ ...
