Obviously trivial, to write, but not having had two drives sortof precluded it. The program should say something a bit more useful than 'tape to tape called'. Actually, the program is optimized for tape to disk and then to back to tape, to facilitate making multiple copies of tapes. It is very fast, will stream tu81's, making use of up to 30 asynch qio's for reading a tape and writing a tape. The major drawback is a blocksize limit of 32767, which is due to the use of rms11 for the disk container file Would anyone be willing to implement the tape to tape function? And of course, I'm open to any other suggestions for improvement.
