True for Sun, but there is a package in the AT&T Toolchest that knows how
to read most of the standard IBM tape formats.  It includes a program
generator that lets you write custom programs that translate the fields in
input records.  Translations are defined for EBCDIC, packed decimal,
binary and floating point fields.

The package has full support for label processing, including support for
multi-dataset tapes and multi-tape datasets.
