For example you wish to do a series of plots with the same limits on the X,Y scales. Normally TOPDRAWER sets the limits automatically according to your data, so you use the command: TD:SET LIMITS X FROM 0 TO 10 Y FROM 0.5 to 1.5 PERMANENT which sets the limits permanently. When you have done the plots you wish to revert to the original default: TD:SET LIMITS Now the limits are reset to automatic limits for the current plot only. The next plot will have the PERMANENT limits. To have automatic limits for all subsequent plots you must: TD:SET LIMITS;SET LIMITS PERMANENT
After using a set command you may "see" what you have done with a SHOW
command. For each set command there is a SHOW command which shows the
current options. For example you may see the limits you have modified
by:
TD:SHOW LIMITS

Additional Information on:
PERMANENT - Makes the current setting the new default. (Default:1.0)
If dx is omitted it is set to the default. If dy is omitted it is the
same as dx.
BLINK
SET BLINK [ON|OFF]
Text or data plotted while this is on will blink. This will only work
with certain devices. The blink attrubute is reset to off at the
beginning of each new plot. If ON or OFF are omitted BLINK is set ON.
(Default:OFF)
CARD
This sets the number of columns per input line for non interactive
input.
SET CARD|INPUT [LENGTH]=[length]
All data past the length is ignored The length must be in the range 20 to 256. See also SET FORMAT. This parameter remains the same when a new plot is started. (Default:256)
You should be careful when using this command. If you extend the input line before extending the format, TOPDRAWER will expect multiple input lines per command.
If length is omitted it is reset to the default value. For interactive
input on the VAX the length is 256 and it is independent of the set
card command.
CHARACTER
SET CHARACTER {TERMINATOR|SEPARATOR|SPECIAL|ALPHA|ILLEGAL|COMMENT |
ENDCOMMENT} "characters"
This redefines the input character set. You may not redefine the
letters "A" to "Z", the numbers "0" to "9", the period "." or the minus
and plus signs "-+". The current definitions are:
1. SEPARATORS = ",/="
2. TERMINATOR = ";"
3. SPECIAL = "@!#$%^&*~`{}|\[]"
4. COMMENT = "("
5. ENDCOMMENT = "("
6. ALPHA = "_"
7. ILLEGAL = all non printable characters.
Special characters may be imbedded inside an option, but may not be the
first character in an option.
CIRCLE
This sets the default size for circles.
SET CIRCLE [SIZE=dx[,dy]] [PERMANENT]
This is same as SET ELLIPSE
PERMANENT - Makes the current setting the new default. (Default:1.0)
If dx is omitted it is set to the default. If dy is omitted it is the
same as dx.
CLEAR
SET {CLEAR|ERASE} {DEFERRED|IMMEDIATE}
1. DEFERRED - After a CLEAR or NEW PLOT command the screen is not
cleared until data is plotted. In other words the current
plot remains on the screen until the new plot appears.
2. IMMEDIATE - The screen is cleared immediately after a CLEAR or
NEW PLOT command.
COLOR
SET COLOR [WHITE|RED|GREEN|BLUE|YELLOW|MAGENTA|CYAN]
[PERMANENT]
(Default:WHITE) This sets the default color of the display or the pen number. This is effective only for the current plot, or until another SET COLOR or SET PEN command. If PERMANENT is specified the current color is the permanent default. See:Command SET PEN
If no options are specified it is set to the WHITE.
COMMAND
SET COMMAND [MAXSUBSTITUTION=n]
This sets the maximum number of command substitutions allowed on a
single line.
(Default:MAXSUBSTITUTIONS=1000)
Ctrl_Z
SE Ctrl_Z [ON|OFF]
Enables or disables the Ctrl_Z key as a means of stopping TOPDRAWER.
(Default:ON)
CYCLE
SET CYCLE [NUMBER=n] [ENTRY[=n]] [WIDTH|INTENSITY=n] [NOCOLOR|WHITE|
RED|GREEN|BLUE|YELLOW|MAGENTA|CYAN] [NOTEXTURE|SOLID|DOTS|
DASHES|DAASHES|DOTDASH|PATTERNED|FUNNY|SPACE] [SYMBOL=sym]
[PERMANENT]
This selects a cycle of attributes to be used when the CYCLE option is
used with HISTOGRAM, JOIN, CONTOUR, or PLOT.
Additional Information on:
Options YEAR,MONTH, or DAY allow you to reset just the selected value.
Instead of MONTH=3 you may also specify MARCH. All 3 may be modified
using the standard YEAR\MONTH\DAY notation.
DEVICE
This selects the unified graphics device and sets options back to
default values. This is equivalent to starting a new plot on another
device.
SET DEVICE [name] ["option_string"]
[SIDEWAYS|ROTATED|ORIENTATION=n]
[LANDSCAPE|PORTRAIT]
[COlOR[=ON|OFF]
[FILE|OUTPUT|DDNAME=filename|CHANNEL=dev:]
[INTERACTIVE|SEQUENTIAL|SLAVE]
[ADD|UNIT=n]
[IDENT=aaaa] [NUMBER=nnnn] [PERMANENT] [WIDTH=n] [HEIGHT=n]
[REVERSE]
This selects the device name. It is modified by the option_string. If
omitted the default is used. See:PERMANENT.
(Interactive Default:TEK)
(Batch Default:PS)
Additional Information on:
PERMANENT - Makes the current setting the new default. (Default:1.0)
If dx is omitted it is set to the default. If dy is omitted it is the
same as dx.
DIGITS
SET DIGITS=n
Sets the number of significant digits displayed in a SHOW DATA command
and the lexicals. The number of digits may be set to a value from 0 to
7. If n=0 then the number of digits is adjusted to suit the display.
If n is omitted it is assumed to be 0.
(Default:DIGITS=0)
ELLIPSE
This sets the default size for the major and semi-major ellipse sizes.
If dy is omitted the ellipse becomes a circle.
SET ELLIPSE [SIZE=dx[,dy]] [PERMANENT]
PERMANENT - Makes the current setting the new default. (Default:1.0)
If dx is omitted it is set to the default. If dy is omitted it is the
same as dx.
ERRORS
SET ERRORS [{DEFERRED|IMMEDIATE|LIST}] [WAIT|PAUSE[=ON|OFF]]
1. DEFERRED - The error messages appear after the plot is finished. 2. IMMEDIATE - The error messages appear when the command is entered. 3. LIST - The error messages appear only in the listing file. 4. WAIT - When error messages are immediate, WAIT causes TOPDRAWER to wait after each message. PAUSE is a synonym for wait.
This option remains the same until changed by a SET ERRORS command.
(Default:IMMEDIATE,NOWAIT)
EXACT
SET EXACT [ON|OFF] [PERMANENT]
Sets the character comparison to be exact rather than case blind.
(Default:OFF)
FILE
This selects the file names for data input, output, and journaling.
SET FILE
[INPUT=filename]
[LIST|OUTPUT=filename]
[JOURNAL=filename]
NOTE
This command is very different from the original SLAC version of
TOPDRAWER.
Additional Information on:
This option remains in effect until changed by a SET FONT command. The
EXTENDED and DUPLEX fonts both use proportional spacing. If you wish
to use a fixed spacing font See:Command SET MODE PROPORTIONAL.
FORMAT
Sets the format used by the Fortran READ statement.
SET FORMAT "format"
This is useful if you wish to skip lines at the beginning of a line
when you are using a list file as input to TOPDRAWER. Normally you do
not need to use this command, unless the data is in an extremely weird
format. The format is limited to 64 characters. (Default:(256A1) The
number of columns is also limited by SET CARD. This option remains the
same until changed by a SET FORMAT command. This option has no effect
on input you enter interactively at the terminal.
Example
If you wish to skip the first 10 columns:
TD:SET FORMAT "(10x,256A1)"
GRID
This causes a grid to overlay the plot when axes are drawn. The grid
lines are lined up with the large tick marks. This acts on the current
plot only a new SET GRID is required for each plot or the options
PERMANENT must be specified. The command must be followed by either a
HIST, JOIN, BARGRAPH or PLOT command to be effective.
SET GRID [ON|OFF] [Y|HORIZONTAL|X|VERTICAL!Z[=ON|OFF]] [SYMBOL[=sym]]
[XY|YZ|ZX[=ON|OFF]] [CYCLE[=ON|OFF]] [OUTLINE[=ON|OFF]]

level=1 to 5. (Default:2) 5 is the brightest (widest). If no
intensity is specified it is set to 2.
PERMANENT - Sets the current width to be the new default.
LABELS
This sets the size and enables the numeric labels on each axis. To
control the default number of ticks see SET SCALE.
SET LABELS [SIZE=n] [CHARACTERS=n] [INSIDE[=ON|OFF] [ALL|TOP|BOTTOM|
RIGHT|LEFT|X|Y|Z] [ON|OFF] [SHIFT=n]
[INTENSITY|WIDTH=n]
[NOCOLOR|WHITE|RED|GREEN|BLUE|YELLOW|MAGENTA|CYAN]
[PERMANENT]
This acts on the current plot only if PERMANENT not specified. If the
parameters are omitted they are reset to the original default. To
control other individual elements of the axes use:
SET AXES, SET TICKS, SET OUTLINE, SET SCALES
(DEFAULT:LEFT ON,BOTTOM ON)

Additional Information on:
Sets a new name for all the selected data sets. If no sets are specified, then all data set names are modified. If the name ends in "%" then the old name is appended to the new name.
Options
1. CONFIRM - If selected Topdrawer will prompt you for each data
set. You repy YES, NO, ALL, or QUIT. ALL will do the rest
without any more prompts, while QUIT skips all the rest.
2. SETS - Selects a range of data sets to rename.
3. SELECT - Selects the data sets by name. WIld characters are
permitted "*" or "%" See:SET EXACT.
Example
TD:SET NAME "My data" SET=5
Data set number 5 has the new name "My data"
TD:SET NAME "My %" SELECT="Your*"
All data sets beginning with the name "Your" are renamed to
"My Your..."
ORDER
This sets the order in which data must be entered. The order is the
same as specified in the set order command. This option remains the
same until the next SET ORDER or NEW PLOT command. This has no effect
on mesh data input.
SET ORDER [[N][R|D]{X|THETA} [fctr]] [[N][R|D]{Y|RADIUS} [fctr]]
[[N][R|D]{Z|PHI} [fctr]] [[N][R|D]U [fctr]] [[N][R|
D]V [fctr]] [[N][R|D]W [fctr]] [SYMBOL] [DUMMY[=n]]
[PACKED[=ON|OFF]] [PERMANENT]
Additional Information on:
(Default:ON)
Additional Information on:
1. RANDOM - The distance following this is random. 2. DOT - Draws a single dot followed by a 0.1" space. 3. DASH - Draws a short dash 0.1" long followed by 0.1" space. 4. DAASH - Draws a long dash 0.3" followed by 0.1" space. 5. SPACE - Adds 0.05" of blank space. 6. SIZE=n - Size of dashes, and the distance between dashes and dots. (Default:0.1) 7. p = distance to draw in inches. If negative it varies randomly. 8. s = distance to skip in inches. If negative it varies randomly. 9. PERMANENT - Makes the current SIZE the permanent default.
You may enter up to a maximum of 20 values or 10 DOT/DASH/DAASH specifiers. Random values vary from zero to the value specified. You may also specify patterns as part of any drawing command. For example: TD:HISTOGRAM PATTERN DOT DOT DASH is the same as ... TD:SET PATTERN DOT DOT DASH; HISTOGRAM PATTERN or... TD:HISTOGRAM DOT DOT DASH See:Command SET TEXTURE
Additional Information on:
See:Command SET COLOR
(Default:1)
If no pen number is specified it is set to 1.
POLAR
SET POLAR [ON|OFF] [DEGREES|RADIANS|GRAD|PERCENT|FULLCIRCLE=n]
[PERMANENT]
This sets up to plot in polar coordinates. Coordinates are (R,THETA,Z) instead of (X,Y,Z) In addition you may select the scale for angle representaton. This affects not only the plotting of data, but also the FFT and TRANSFORM commands. 1. ON|OFF turn the polar coordinates on or off. (Default:ON) 2. PERMANENT - Sets these parameters permanently. 3. DEGREES... - Selects angle representation (Default:DEGREES) A. GRAD - (0-400) B. DEGREES - (0-360) C. PERCENT - (0-100) D. RADIANS - (0-6.2831853) E. FULLCIRCLE=n - (0-n)
This feature is not fully implemented. You still set the limits in X,Y,Z coordinates, and automatic scaling centers the origin. When you plot, the axes are not automatically generated if polar coordinates are on. You must manually plot the axes with the command: PLOT AXES. If you wish the X and Y axes to be scaled the same way you should. TD:SET LIMITS SCALE See commands:X,SET ORDER,SET STORAGE,SET SPHERICAL
Example
TD:SET POLAR FULL=1.0
Angles represented by a number from 0 to 1.0 range from 0 to 360
degrees.
PROMPT
SET PROMPT [MAIN|PAUSE] [ERASE] [TOP] [BOTTOM] [BELL] [nn]
["prompt_string"]
This sets the current prompt string with a maximum of 80 characters. If a null or blank string is used, then there is no prompt. If a prompt has imbedded blanks it must be enclosed in quotes. The prompt string remains the same until a new one is selected. 1. MAIN - Is the main prompt string. (Default:"TD:") 2. PAUSE - Is the prompt string used when a NEW PLOT is started. (Default:"PAUSE:") 3. ERASE - The prompt erases the screen (ANSI terminal). This erases text from a VT-1xx/2xx compatible terminal. This does not erase TEKTRONIX graphics, but REGIS graphics will be erased. This must be precede the string. 4. TOP - The prompt is at the top of the screen (ANSI terminal). 5. BOTTOM - The prompt is at the bottom of the screen (ANSI terminal). 6. BELL - This rings the bell for each prompt. 7. nn - This inserts a control character (0-255) into the string. 8.
This command is useful for controlling the prompt for different types of terminals. On some terminals you can control the position of the prompt, so that it will not interfere with the plot, while on others, you may not want any prompts.

Additional Information on:
To produce shadowing you must select at least one plane to shadow the plot in (XY,YZ,ZX).
Additional Information on:
1. n - The shield number between 1 and 4. If unspecified the next available shield is used.
2. OFF - Turns the n'th shield off. If n is not specied all shielded areas are turned off.
3. FROM|TO - Allows you to specify the limit of the shielded area. If no limits are specified the current window is shielded.
4. DATA - Specifies the limit in data coordinates.
5. TEXT - Specifies the limit in text coordinates.
6. CURSOR - You use the cursor to specify the limits.
example
TD:SET SHIELD FROM 1,2 to 3,5
Sets a shielded area in text coordinates.
TD:SET SHIELD DATA FROM Y=5
Shield all data from Y=5 for all X values.
SIZE
This sets the physical size of the plot. Once set it remains the same
until a new SET SIZE command is issued. This command should only be
used immediately after a NEW PLOT command or a SET DEVICE command. It
may not be used after any commands that plot data.
SET SIZE [[X=]x [BY|Y=] y]
[UNITS=units] [CM|CENTIMETERS|MM|MILLIMTERS|METERS|INCHES]
[MAGNIFY|REDUCE=factor]
[SIDEWAYS|ROTATED|NORMAL|ORIENTATION=n]
[MARGINS=[nl,[nr,[nb,[nt]]]]] [LEFT=n] [RIGHT=n] [BOTTOM=n]
[TOP=n]
If no options are specified the sizes are reset to the defaults.
(Default:NORMAL 13 by 10 inches MARGINS=0)
Additional Information on:
This sets up to plot in spherical coordinates. (THETA,R,PHI) instead of (X,Y,Z). The data in X is now interpreted as THETA, Y is intepreted as R and Z is intepreted as PHI. The data is not modified, just reinterpreted. R=sqrt(X**2=Y**2+Z**2) THETA=ATAN2(Y,X) PHI=ATAN2(sqrt(x**2+Y**2),Z)
NOTE: There is no universally accepted convention for THETA or PHI. Various books use different conventons. I have adopted a convention that gives THETA the same definition in both spherical and polar coordinates.
1. ON|OFF turn the spherical coordinates on or off. (Default:ON) 2. PERMANENT - Sets these parameters permanently. 3. DEGREES... - Selects angle representation (Default:DEGREES) A. GRAD - (0-400) B. DEGREES - (0-360) C. PERCENT - (0-100) D. RADIANS - (0-6.2831853) E. FULLCIRCLE=n - (0-n)
You still set the limits in X,Y,Z coordinates, and automatic scaling
centers the origin. When you plot, the axes are not automatically
generated if spherical coordinates are on. You must manually plot the
axes with the command: PLOT AXES.

[RECURSOR] [CURSOR] ]
This sets the range of data used by the lexicals. If any changes are
made to the data you need to use this command again.
Additional Information on:
(Default:SYMBOL,X,Y,DX,DY)
ALL selects all coordinates. If this command is used without any options, the storage is reset to the default. If all 3 coordinates X,Y,Z are included in storage, 3-d plots are turned on.
If DX, the error on X, is selected then X is also selected. If NDX is selected then both DX and X are selected. Likewise DY,DZ,..DPHI automatically select Y....PHI. SYMBOL, X and Y are always included in the storage. All other variables must be declared.
The NDX is the negative half of the error bar while DX is the positive half. If NDX is not in stoage then DX specifies both halves. Similarly NDY and NDZ are the negative halves of the Y,Z error bars.
If THETA is specified polar coordinates are enabled permanently. If PHI is specified spherical coordinates are enabled.
SIZE=n allows you to pick the number of words of storage to allocate for the VAX. This is not necessary, but it may save time since you may preallocate the storage and avoid multiple automatic storage expansion. Normally the amount of storage needed for regular data is about n*d+4 where n is the number of points and d is the number of coordinates available in storage (SYMBOL,X,DX,Y,DY,....). For mesh data it is ((n+1)*(m+1)+4)*d+4 where n and m are the mesh dimensions and d is 1 for regular mesh data or 2 for data with errors. If you have a name for the data set it takes up 1 storage location for every 4 characters.
Example
TD:SET STORAGE X Y SYMBOL
To see the current storage use the command: SHOW STORAGE.
TD:SET STORAGE SIZE=<4+101*201+20>
Preallocates storage for a 100 by 200 mesh with an 80 character name.
SYMBOL
This selects the default symbol
SET SYMBOL "xx" [SIZE=n] [THETA=n] [PHI=n] [ANGLE=n] [PERMANENT]
If no parameters are specified the symbol and size are set to NONE and
2 and the angles are turned off. In other words SET SYMBOL is the same
as SET SYMBOL=NONE SIZE=2.
This command determines the symbol plotted data that have no symbol. If you SET SYMBOL before reading data the symbol is assumed for the data you are reading. See:Command READ POINTS and PLOT.

1. SOLID - Solid line 2. DOTS - Dotted line 3. DASHES - Short dashed line 4. DAASHES - Long dashed line (3x) 5. DOTDASH - Dot-dash line 6. SPACE - Adds an extra space between dots/dashes 7. PATTERNED - Line determined by SET PATTERN. 8. FUNNY - is a dot at the ends of each line segment. This is generally only useful for joined and smoothed curves. 9. PERMANENT - Sets the current texture to be the permanent default.
(Default:SOLID)
If no options are specified it is set to SOLID. When a new plot is started the texture is set to the permanent default.
If you specify more than 1 texture option, or use the option PATTERN, then a patterned texture is assumed and the pattern is generated. When FUNNY precedes any other texture specifier then it is generated randomly.
