As Table 1 shows, the format identifier (FID) in GTF trace records is a one-byte hexadecimal number that is used to determine the name of the GTFTRACE module you can use to format USR records. See z/OS MVS IPCS Customization for information about the GTFTRACE formatting appendage for formatting USR trace records.
