William, Surely you know that this isn't a case of "just wanting to have them too" but rather part of the ongoing effort to keep the two standards aligned functionally. This also includes the binary segment in X12 and the package in EDIFACT as well as the Associated Data transaction set. Shame on you! Rachel Since EDIFACT had repeating data elements, X12 just had to have them also! So in 004020, ISA11 became the placeholder for the single character Repetition Separator; the ISA has always had provision for a composite data element separator in ISA16 D.E. I15 Component Element Separator long before there were any composite data elements, first introduced in 003030. If you send any transaction set which uses segments with repeating data elements, you will have to use an ISA with "00402" or newer in ISA12 D.E. I11 Interchange Control Version Number. William J.
