Appendix D. Laurel and MSG101Appendix D. Laurel and MSGThis section addresses the relationship between MSG and Laurel. MSG users must thoroughlyunderstand the contents of this section before trying to use Laurel for the first time. If you don'tuse Maxc or you have never used MSG, you may skip this section entirely. Message.txtIf you are an MSG user on Maxc and become a Laurel user, then your Message.txt file on Maxcwill become your Laurel in-box. Getting new mail (with Laurel) will move messages from Maxcto your Alto disk, emptying Message.txt. This makes it very inconvenient to continue to use bothLaurel and MSG, for once you have mail files on your Alto disk, MSG can no longer access them.Furthermore, MSG and Laurel maintain mail files in formats that are incompatible. You cancontinue to use MSG to maintain mail files on Maxc, and you can use Laurel to maintain mailfiles on your Alto, but you cannot move mail files back and forth. If you want to convertcompletely to Laurel, you can move MSG-constructed mail files to your Alto for use by Laurel, asexplained below. However, this is a one-way street; once on your Alto the files cannot convenientlybe moved back to Maxc and processed by MSG.Mail file philosophyLaurel encourages you to use your default mail file (Active.mail) as a temporary storage area, notan archive. Accordingly, deleted messages are expunged whenever you leave Laurel or shift yourattention to another mail file. There is no analogue of MSG's Quit command (which preservesdeleted messages); Laurel's Quit is like MSG's Exit. If you wish to classify messages, use markcharacters (section 2.3.2). Eventually, selective display on the basis of mark characters may bepossible. Use separate mail files to obtain an archive facility. Laurel's performance will be betterand your screen will be less cluttered.OverwriteLaurel doesn't have a command corresponding to MSG's Overwrite. However, the same effectcan be obtained by selecting Mail file with BLUE.Processing your mail away from an AltoYou can use MSG from any reasonable terminal dialed to Maxc or connected to the Arpanet, butyou can't use Laurel without an Alto. Consequently, if you have no Alto available and wouldlike to process your mail, you must use MSG. If you observe a few conventions while using MSG,you will not need to reprocess your old messages with Laurel. Thus, you can use MSG from ahome terminal or when you are out-of-town, and revert to Laurel when your Alto is again athand.!/fpXqEfp g^rs gZCpqpqptp gXx(t)p gV!qp' gR"t gNp qpJ gL< gK tp: gIP qp3qp gG qp ? gEqp, gC t.p gB%$qp) g@[tR g>(ut g: g6pAtp g4 T g2:qp g12sp qp g/hO g-7/ g+' g'Ft g#p0qp% g" spqp g}t& g p qpI gAR gv'qpt.up gtpqp g8" g g=W<-LAUREL MANUAL102As long as you manipulate only your Message.txt file with MSG, Laurel will note what you havedone when you perform a New mail command. (Remember, Laurel uses Message.txt as your in-box.) Specifically, deleted messages in Message.txt will not be retrieved, and theexamined/unexamined status of each message retrieved will be reflected in the mark field inLaurel's table-of-contents.Moving mail files from MaxcBecause MSG and Laurel have incompatible mail file formats, you cannot simply move yourarchival mail files to your Alto disk and expect Laurel to read them. The following procedureshould be followed:1.Start Laurel, and use the Run command to run Chat.laurel.2.Using Chat, login to Maxc.3.Using Chat, append the desired mail file, say Name.txt, to Message.txt:@Append Name.txt Message.txt CRIf Message.txt is empty, you must undelete it first, by giving the command:@Undelete Message.txt CR4.Point the cursor at Mail file, click RED, and supply the file name Name.5.Point the cursor at New mail and click RED. After the messages have arrived, ensurethat no unexpected ones have been included at the beginning and/or end of the file.(New mail might have arrived on Maxc before or after step 3.) Move any extraneousmessages to "Active.mail".6.Repeat steps 3 through 5 for each mail file on Maxc.7.Logout from Maxc and Quit from Chat.laurel. You may now proceed in Laurel.Fortunately, once you have moved all of your files in this way, you won't have to do it again,since Laurel will maintain them in its own format on your Alto disk.$fpqpXq gfp g_tpqp g]Ksp9 g[c=d gYF gW gS_t gOpqpL gN#> gLX]Hsp]Et]B.tpS@7tpq>K`<]9wpspqptp]6sp qp)4:L2p60]-34]); g&OT g$D g$>
