CFFK@MIT-MC 04/02/82 09:40:35 To: PLOT2 at MIT-MC TEKS1:TRUE; so S1 Grinnels.  Date: 2 April 1982 09:40-EST From: Charles F. F. Karney Subject: :SENDS clobbering Macsyma To: JFJ at MIT-MC, JONL at MIT-MC, JPG at MIT-MC cc: PLOT2 at MIT-MC I now 'bind' TTY-RETURN during a plot, so the chances of :SENDs clobbering things are lessened. So could you (JFJ) try your CRASH > again and let me know how things turn out.  Date: 25 September 1981 09:48-EDT From: Charles F. F. Karney To: INFO-PLOT2 at MIT-MC cc: JEFFC at MIT-MC PLOTMODE:PRINTING$ has been changed a little. (1) The output of the plot is now suppressed by a ^W or TTYOFF:TRUE$ (2) The output is directed to a WRITEFILE if it exists. (3) If TTYOFF:TRUE$ (or a ^W is in effect) then PLOT2 will not wait for a character to be typed after the plot (even if WAIT:TRUE). All this means that (WRITEFILE(),TTYOFF:TRUE, some plots, CLOSEFILE(FOO),TTYOFF:FALSE); will give you the plots in your WRITEFILE and not on your screen and that you won't have to sit and type spaces. Unfortunately, you can't relinquish terminal (with ^Z^P) because PLOT2 needs to find out some properties of the terminal. Maybe this can be fixed sometime.  Date: 10 August 1981 14:11-EDT From: George J. Carrette To: CFFK at MIT-MC cc: PLOT2 at MIT-MC DOVARD takes a PRESS file and inserts an ARDS file into it on the specified PAGE. The font is presumably specified by the press file. The press file I'm using now is a single bare page created by "R" from the file "MAXSRC;.PLOT TMPLT" I have written DOVARD_FILE so that you can call it from the PLOT2 package if you want. (Notice, it isn't an FSUBR, even though it takes a filename argument.) -gjc  CFFK@MIT-MC 08/10/81 09:42:55 To: PLOT2 at MIT-MC, GJC at MIT-MC Presumably DOVARD_VIEWPORT should be superceded someday by the PLOTLFTMAR, PLOTSCALE etc. options. Question: What font does the Dover use in this process? (PLOT2 needs to know its width.) Also I believe RHB was mentioning something about being able to splice plots into a text file. Is that right? What do you do? Insert the ards file into the text file and run DOVARD over it? Does DOVARD know how to break text into pages?  Date: 9 August 1981 11:52-EDT From: Charles F. F. Karney Subject: Revised documentation + a couple of other things To: INFO-PLOT2 at MIT-MC (1) SHARE;PLOT2 USAGE has been completely revised. The section of easy examples at the beginning of the old version has been moved to SHARE;PLOT2 PRIMER. Because PLOT2 USAGE has grown so long, it will shortly be made into an illustrated report. So you are encouraged to read these files and let me know of any ways in which they can be improved. (Within a week if possible.) (2) CFFK;EDIT FASL works again. (Some change to TEKPLT FASL made after I left MIT had caused it to stop working. I finally got hold of a Tektronix on which I could debug things.) There is a parameter EDITCR (default FALSE) which governs whether the program expects your terminal to send out a following the position of the cross hairs. (This is determined by a strap setting in the terminal.) So if EDIT seems not to be working try EDITCR:NOT(EDITCR);. (3) There is a flag HARDCOPY (default FALSE). If it's TRUE, a HARDCOPY() is done after each plot (provided WAIT:TRUE). This enables you to easily switch from an interactive mode (where you view the plots on the screen and selectively request hardcopies by typing linefeed) to a batch mode. For instance you could say (PLOTMODE:'XGP, TTYOFF:TRUE, BATCH(...)); and then you get out of your Macsyma and get on with other business. (The usual caveats about being present when plots are coming out of the XGP apply, of course.) (4) PLOT2ERROR may take the value FALSE. This is the same as PLOT2ERROR : PLOTUNDEFINED, and it causes the point not to be plotted.  GJC@MIT-MC 08/07/81 23:45-EDT To: INFO-MACSYM Subject: New output device for PLOT2 users. The command DOVARD_FILE takes an ARDS file produced by PLOT2 (when in the PLOTMODE(G) mode), and creates a PRESS file suitable for output to the DOVER. The command DOVER_FILE will queue the file. For example, after you have done PLOTMODE(G,GR), and PLOT2(X,X,0,1); you can then do (DOVARD_FILE(),DOVER_FILE()); to queue the plot. In the near future the HARDCOPY and PLOTMODE commands may be extended to include this option, calling the functions in question for you. Advantage: The DOVER output device is *many* times faster than the XGP and its use is *much* less a drain on the system than then the GLP/XGP combination. Output is also of higher quality. Disadvantage: DOVER has a higher chance of jamming, and complicated 3d-plots may bomb out.
