Trailer record in FCC

Hi All,

I want to pick up file by using FCC. The structure of file is as follows:

abbcccddddeeeee

abbcccddddeeeee

.

.

.

TRzzzxxyw

(First lines are multiple records)

Here the last record is Trailer record which starts with 'TR' always. With first record i know how to handle it by using fieldFixedLengths parameters.

But how can i pick up trailer record which will always start with 'TR'?

Thanks.
