In or out of a PDSE spanned records make LRECL > BLKSIZE possible. Attitudes toward RECFM=VBS probably reflect a mixture of 1) longevity and 2) experience with scientific computation. Unformatted FORTRAN i/o for the IBM 704 used them, and its implementation using 'green words' was essentially the same as the one in use today. They were devised to treat the problem of outputting, say, an array x(100,100) of 36-bit words, which would have been difficult to fit into a single tape record block of the time.
