The program MTTOPT copies a magtape file to paper tape. The magtape should be written in binary, with physical records which are a multiple of 4 bytes. The paper tape will have a leader and trailer of nulls. The Paper tape punch, alas, is not connected to the DEC-10. If you are going to use this program, please call 543-9275 and ask Ron or Bruce what can be done about it. .KJOB .
