Variable length record format
Variable length tape blocks may be bannered or unbannered and
may contain one or more variable length logical records (refer to
figure 10-4). The actual block length is given by a three octal
character binary number if the input tape is recorded in odd parity.
The actual block length is given by a four octal character decimal
number if the input tape is recorded in even parity. The block length
includes its own length plus the banner character, if present.
The actual record length for a record is given by a two octal character
binary number if the input tape is recorded in odd parity. The record
length is given by a three octal character number if the input tape is
recorded in even parity.
