Back  RFI # 2207: Segment Delimiters

Formal vs. Informal Help Informal Formal


Tracey Eaddy


A receiving system should be capable of reading the ISA segment to determine all delimiters being used in the file, including the segment terminator. Is it necessary to negotiate what delimiters are used? Are carriage returns, line feeds, or a combination of both acceptable to be used as a segment terminator?
