It sounds like you’re working with a fixed-width file ( .fwf ) that follows a specific record layout — likely from a legacy system, mainframe, or EDI feed. The filename cp_7_9_12_v17_0.fwf suggests it may be a control parameter or copybook-style layout, possibly with record lengths or field positions derived from a COBOL copybook.
