This is not exactly un*x but it may be useful at times.

You can read ANY tape on VM/CMS if it has physical records that are 
<= 32760 bytes. Use the following:

	Mount the tape unlabeled as 181.

	FILEDEF IN TAP1 (RECFM U LRECL 32760 BLOCK 32760
	FILEDEF OUT DISK foo bar a (RECFM U LRECL 32760 BLOCK 32760
	MOVEFILE IN OUT

This will result in a CMS V-format file with the data from the first file
on the tape. Each line of the file is a physical record from the tape.
Repeat the filedef of OUT and the MOVEFILE command to read subsequent files.
The COPY command does a good job of character conversion. You will need to
write a program to look for end-of-lines and rewrite your file.

It's not the cleanest solution, but it's cheap.
