Definition(s)
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.
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.
type
Specifies how the block length is coded:
BIN (binary)
DEC (decimal) (=printable)
The default is BIN.
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.
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.
