11 I now 'bind' TTY-RETURN during a plot, so the chances of
12 :SENDs clobbering things are lessened. So could you (JFJ)
13 try your CRASH > again and let me know how things turn out.

20 PLOTMODE:PRINTING$ has been changed a little.
21 (1) The output of the plot is now suppressed by a ^W or TTYOFF:TRUE$
22 (2) The output is directed to a WRITEFILE if it exists.
23 (3) If TTYOFF:TRUE$ (or a ^W is in effect) then PLOT2 will not wait
24 for a character to be typed after the plot (even if WAIT:TRUE).
26 (WRITEFILE(),TTYOFF:TRUE, some plots, CLOSEFILE(FOO),TTYOFF:FALSE);
27 will give you the plots in your WRITEFILE and not on your screen
28 and that you won't have to sit and type spaces.
29 Unfortunately, you can't relinquish terminal (with ^Z^P) because
30 PLOT2 needs to find out some properties of the terminal.
31 Maybe this can be fixed sometime.

38 DOVARD takes a PRESS file and inserts an ARDS file into it
39 on the specified PAGE. The font is presumably specified by
40 the press file. The press file I'm using now is a single bare
41 page created by "R" from the file "MAXSRC;.PLOT TMPLT"
43 I have written DOVARD_FILE so that you can call it from the PLOT2
44 package if you want. (Notice, it isn't an FSUBR, even though it
45 takes a filename argument.)

51 Presumably DOVARD_VIEWPORT should be superceded someday
52 by the PLOTLFTMAR, PLOTSCALE etc. options. Question:
53 What font does the Dover use in this process? (PLOT2 needs
55 Also I believe RHB was mentioning something about being
56 able to splice plots into a text file. Is that right?
57 What do you do? Insert the ards file into the text file and
58 run DOVARD over it? Does DOVARD know how to break text into

63 Subject: Revised documentation + a couple of other things
64 To: INFO-PLOT2 at MIT-MC
66 (1) SHARE;PLOT2 USAGE has been completely revised. The section of easy
67 examples at the beginning of the old version has been moved to
68 SHARE;PLOT2 PRIMER. Because PLOT2 USAGE has grown so long, it will
69 shortly be made into an illustrated report. So you are encouraged to
70 read these files and let me know of any ways in which they can be
71 improved. (Within a week if possible.)
73 (2) CFFK;EDIT FASL works again. (Some change to TEKPLT FASL made after
74 I left MIT had caused it to stop working. I finally got hold of a
75 Tektronix on which I could debug things.) There is a parameter EDITCR
76 (default FALSE) which governs whether the program expects your terminal
77 to send out a <cr> following the position of the cross hairs. (This is
78 determined by a strap setting in the terminal.) So if EDIT seems not to
79 be working try EDITCR:NOT(EDITCR);.
81 (3) There is a flag HARDCOPY (default FALSE). If it's TRUE, a
82 HARDCOPY() is done after each plot (provided WAIT:TRUE). This enables
83 you to easily switch from an interactive mode (where you view the
84 plots on the screen and selectively request hardcopies by typing
85 linefeed) to a batch mode. For instance you could say (PLOTMODE:'XGP,
86 TTYOFF:TRUE, BATCH(...)); and then you get out of your Macsyma and
87 get on with other business. (The usual caveats about being present
88 when plots are coming out of the XGP apply, of course.)
90 (4) PLOT2ERROR may take the value FALSE. This is the same as
91 PLOT2ERROR : PLOTUNDEFINED, and it causes the point not to be

96 Subject: New output device for PLOT2 users.
97 The command DOVARD_FILE takes an ARDS file produced by PLOT2 (when in
98 the PLOTMODE(G) mode), and creates a PRESS file suitable for output
99 to the DOVER. The command DOVER_FILE will queue the file.
100 For example, after you have done PLOTMODE(G,GR), and PLOT2(X,X,0,1);
101 you can then do (DOVARD_FILE(),DOVER_FILE()); to queue the plot.
103 In the near future the HARDCOPY and PLOTMODE commands may be extended
104 to include this option, calling the functions in question for you.
106 Advantage: The DOVER output device is *many* times faster than the XGP
107 and its use is *much* less a drain on the system than then
108 the GLP/XGP combination. Output is also of higher quality.
109 Disadvantage: DOVER has a higher chance of jamming, and complicated
110 3d-plots may bomb out.
