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 minus (-) may be used to specify a positive or
negative adjustment.
