Each of the parameters in this format have a different meaning -
V - Blocks as well as logical records are of variable size. The first 4 bytes of each block (and logical record) describes its length.
B ? One or more logical records reside in each block.
S- For fixed-size records, it indicates that no short blocks are permitted anywhere but the end of the data. For variable-size records, it indicates that a logical record can span more than one block.
