FHS segment
The FHS segment is used to head a file (group of batches) as defined in Section 2.10.3, "HL7 batch protocol". 2.15.6.0 FHS field definitions 2.15.6.1 FHS-1 File Field Separator (ST) 00067 Definition: This field has the same definition as the corresponding field in the MSH segment. 2.15.6.2 FHS-2 File Encoding Characters (ST) 00068
The shape of one line
required optional
FHS-2 and its value arrives as FHS-1, so the receiver stores File Encoding Characters as File Field Separator.This page carries the FHS field table as published and nothing beyond it. The field notes, vendor behaviour, FHIR mapping and parsing guidance that thePID page has are still to be written for FHS.

No message structure in v2.5.1 carries FHS, and no other segment is linked to it here. The standard defines the segment on its own.
