Thus you have created an IBM OS-format tape with variable-block
record format and EBCDIC encoding; blocksize and logical record
length as shown.

:
These programs were used successfully for many years on Ultrix 1.0 and later,
and then SunOS 4.0 and 4.1. We have never tried them on Solaris. It looks
like some tinkering might be necessary; either record boundaries are not
being recorded correctly by cutape, or ostape is not identifying them.
Questions:
. Do you really need to write IBM mainframe format tapes?
If not, you might want to try cutape's "a" option to write
ANSI "D" format, and then you can use ansitar to read them.
. Assuming you really do intend to write IBM EBCDIC tapes, you'll
need to find out whether cutape-generated tapes can be read
on a real IBM mainframe. If so, then ostape is at fault.
If not, then cutape needs changes for Solaris.
