Inter-Office MemorandumToDistributionDateJune 16, 1980FromTim DiebertLocationPalo AltoSubjectInterim MFTP Magnetic TapeOrganizationPARC/CSLProgramXEROX Filed on: [IVY]Docs>InterimMFTP.memo, .pressThis document describes the interim Magtape File Transfer Program originally written by GlennKrasner of SSL. The Program may be retirieved from [IVY]Software>MFTP.run. Theprogram is written in Bcpl and should run on all of the PARC personal computers. The program isinteractive in nature and therefore does not understand command line entries. The program isinvoked by: MFTP.runThe program will respond with:Magtape File Transfer Program, version 1.2, June 9, 1980Connect to (CR to exit program):The present network name of the tape serving Alto is Saintpaulia. Once a connection is established,MFTP will respond with:Open!The program will then prompt for a command. The currently supported commands are:? (Help), c(lose connection), r(ead), w(rite), f(ile skip forward), b(ack skip file) and u(rewind).All commands should be self explanitory except for one caveat related to back skip file. Since tapesare a sequentially recorded media, files are deliniated with a special record called an EOF ortapemark. When a tape is forward skipped, the position of the tape head after the operation is afterthe EOF mark. If a back skip file is performed with the tape head positioned after an EOF theback skip will only skip over the EOF and not over any data records. Therefore the back skip mustbe performed again if the data records are to be skipped over as well.]gpi c8q]r -q7BrX ]q]r -q7Br Yq]r-q 7Br]WSsr M8 GW Fk?
