ISA (Interchange Control Header Segment)

The ISA is a fixed record length segment and all positions within each of the data elements are required. The first element separator defines the element separator used through the entire interchange. The segment terminator used after the ISA defines the segment terminator to be used throughout the entire interchange.

The Input Data column below contains text in [bracketed italics], which indicates special input data dependent on sender, time, date, etc.
