Parameter Definition(s) Offline Online DJDE
ADJUST=
value
value
Specifies the block adjustment length. This length is
a constant integer added to or subtracted from the
value in the block length field of every tape block. The
resulting value is the true block length. The range for
a value is
-127 to 127 and must be less than the block length
parameter (LENGTH). The character plus (+) or mi-
nus (-) may be used to specify a positive or negative
adjustment.
The default is 0.
Y N N
CONSTANT=
sc
sc
is a string (hexadecimal, octal, or character) constant
which signals block-end. The length of the constant
may be from one to four bytes.
There is no default. If not defined, there is no block-
end-string.
Y N N
FORMAT=
type
type
Specifies how the block length is coded:
BIN (binary)
DEC (decimal) (=printable)
The default is BIN.
Y N N
LENGTH=
value
value
Specifies the length, in bytes, of the longest physical
block (an integer in the range 12 to 24,576). The de-
fault is 1330. For offline processing, the tape label
contents may override a coded LENGTH parameter,
but this length is still limited by the above maximum
value.
The default is 1330.
Y N N
LMULT=
value
value
Multiplied by the value in the length field (refer to
LENGTH parameter) to compute the number of bytes
in the block. A value is an integer in the range of 1 (the
default) to 15.
The default is 1.
Y N N
