Note that a “space sequential filemarks” is a space to the first occurrence
of n filemarks written sequentially.
A SPACE command in the form “SPACE N blocks” will halt with GOOD
status after the Nth block, or with CHECK CONDITION status on any
occurrence of Filemark, EOD, BOM/P, or EOM/P. A command “SPACE
N Filemarks” will halt on the Nth Filemark with GOOD status on any
occurrence of EOD, BOM/P, or EOM/P.
Depending on the size of blocks, read ahead data in the buffer allows
some spacing requests to be satisfied without actual tape movement.
