3.36.3 Space to EOD
The Count field is ignored in the space-to-EOD function.
In the space-to-EOD function, the tape is positioned such that a subsequent WRITE
command appends data to the last recorded information on the tape. This
positioning is done at high search speed.
The space-to-EOD function is useful in support of user-defined directories located at
the end of recorded data.
If physical EOM is encountered while spacing to end of data, Check Condition
Status is returned and Extended Sense is set to Medium Error.
If unrecoverable data error is encountered, Check Condition Status is returned,
Extended Sense Key is set to Medium Error, and Extended Sense Valid bit is set,
indicating Residual Length is non-zero.
