What is the meaning of FNC1?


FNC1 is used as a field separator for variable length application identifiers (AIs) and is encoded by the sequence \F. For instance, the batch number is a variable length data field and needs an FNC1 as terminator if the data length is lower than the maximum of 20 characters. Please note: • For encoding the FNC1 you have to activate Translate Escape Sequences. • Do not use FNC1 after the last data field. • Do not use FNC1 if the maximal field length is used.
