Explanation

QSAM (Queued Sequential Access Method) supports several recording modes for organizing data in files. F (Fixed) means all records are the same length, V (Variable) allows records of different lengths with length prefixes, U (Undefined) is for unformatted data, and S (Spanned) allows records to span multiple blocks. These modes determine how physical records are stored and accessed on mainframe systems.
