Definition(s)
value
Specifies the length in bytes of the field containing the
block LENGTH specified above. The size is an inte-
ger in the range of 0 (the default) to 5. If size is set to
0, the block length field is not considered to be part of
the block, and the length of a block, on tape, is the ac-
tual block length.
The default is 0.
value

the number of bytes from the first byte of a block to
the block length field. A value is an integer in the
range 0 (the default) to LENGTH-LTHFLD-1.
The default is 0.
