1	TVG
 TVG is a powerful utility program used to create neat, professional-
 looking view-graphs.  A series of commands used to make a slide may
 be saved and re-used or modified.   The commands are:

 BYE		Logs you out of TVG, same as ^Z.
 CLEAR		Clears all text and box definitions; the
 		default values are unchanged.
 E<text>	Enter new text to be associated with the
 		next available identifier.
 F [n]		Plot final viewgraph on TTn:.
 MA [l] d	Modify the alignment of TEXTl to d, where
		D = 0. (LEFT) AND D = 1. (RIGHT). Default: d=0.
 MB l		Make Box. Draw up to 32 connected line segments.
 MC [l] n	Modify the character set of TEXTl to n. Default n=3.
 MO [l] d	Modify the orientation of TEXTl to d degrees. Default: d=0.
 MP l		Modify the position of TEXTl to that of the
 		crosshair input.  The alignment can also be chosen if 
 		either an L, C or R is typed to set point.
 MS [l] d	Modify the size of TEXTl to d inches. Default: d=.25.
 MT l<text>	Replace TEXT l with new text.
 N n		Place n ticks on right side during REDRAW.
 R		Redraw with identifiers.
 S t		Save as file named t.
 U t		Unsave from file named t.

	where [l] is the tag letter identifier
 
 To generate a final viewgraph and copy (if TVG is a foreign command, 
 type:
       $TVG filename.ext[/switches]

 Where "filename.ext" is the name of the file in which the viewgraph
 description is saved. (The default extension type is .TVG).  Type
 HELP TVG SWITCHES for help on command line switches

 Type HELP TVG BEGIN for how to start TVG.  Type  HELP TVG command  for help
 relating to a specific command.  
2	SETS

SETS is a seperate program which can be used to generate a complete display
of the specified character sets with the exception of the <SP> character.
The <SP> is a space in all sets except in character set 9 where it is a 
half-<SP>.  This program currently only works correctly on the 11/45 system.
If you need to know what the sets look like, request a Xerox of the character
sets (FEXXXX) from the FED Secretary.
!
! The screen will erase and you will be asked if you want fonts(F) are all(A)
! characters of a given set displayed.  If you type 'F', a sample of each
! set will be drawn.  If you type 'A' so as to see all characters of a set
! displayed,  the screen will erase and then the following question will 
! appear,
! 
! 		Character sets: 
! 
! Enter the minimum [and maximum] set numbers you wish samples of.
! The program will automatically generate hardcopies.  Type ^Z to exit.  
!

2	SWITCHES

	TVG can specify an indirect command file on its command line
	of the form

	TVG @filename
		or
	TVG filename[/-FI/MG:N.]

	where
	/-FI surpresses the filename identifier 
		at bottom right of figure

	/TE:n means plot on terminal n  (*** DOES NOT YET WORK ON VAX)
	/MG:n.nn is magnifaction factor for HCMAG

2 START
 To initiate TVG, Type 
 
	$TVG      (if a foreign command)
	$UTL TVG  (if invoking as utility)
   
 or use the VAX Professional Workstation Graph Master Menu.
 
 The screen of the plotting terminal will blank, bottom and side
 axes will be drawn, and the prompt TVG> will appear.  Your first
 command will be either
	E<text>		to enter a line of text, or
	MB	  	to modify (enter) a box or line segment shape
 
 An identifying tag letter (beginning with capital A) will be
 assigned to this entry.  This tag identifier will be used in
 subsequent commands to refer to the entry.
 
 After either of these commands, the cross-hairs will become visible.
 For entry of text, position the cross-hairs where you would like the
 text, and type either L, R, or C (see HELP for the MP command for
 details).  If you wish to see this entry, use the R command to re-draw
 the screen.  The text string entered will be plotted.  For entry of boxes
 or lines, position the cross-hairs at each point in the line or box, and
 type any character except C or E. (The space bar is useful here).
 Line segments will be produced between these points.  Use C or E 
 to terminate the entry.  See HELP for MB for details.
 
 To enter additional text strings or figures, use the E or MB
 commands.  You can change the default size, orientation, character set,
 or allignment by using the commands MS, MO, MC, or MA without specifying an
 identifying tag.  All subsequent entries will have these characteristics.
2 BYE
 The BYE command (or ^Z) is used to terminate TVG.  Before TVG exits,
 the question "Have you saved this? [Y,n]" will appear.  To exit,
 type Y.  To continue in TVG, type N.  This question is designed to
 remind you to save your new or modified TVG file.
2 CLEAR
 The CLEAR command is used to wipe all text and box definitions, while
 remaining in TVG.  Any default definitions that have been reset remain
 reset.
2 E
		E<text>
 
 The E command is used to enter text.  The next available tag
 identifier (beginning with capital A through lower-case z) will
 be assigned; and is used to reference that text in subsequent
 commands.  (i.e., the MT B command is used to modify the text string
 tagged 'B'.)
 The default Hershey characteristics for entry are character set #3,
 orientation of 0 degrees with the X axis, left-justified allignment,
 and letter size of 0.25 inches.  To change these characteristics,
 see the MC, MO, MA, and MS commands.
2 F
 
 The F command is ued to draw the viewgraph in final form (without
 tags or axes).  After the F command is used, typing a <cr> will
 cause the screen to blank, and the TVG> prompt to re-appear.
2 MA
 The command MA is used to modify the allignment of text strings.
 Allignment is defined as either 0. (left-justified) or 1. (right-
 justified).
 If the command is used with a specific tag identifier,
	MA B 1
 only that string is re-alligned.  If the command is used without
 an identifier,
	MA 1
 the default allignment is changed.  The initial default allignment
 is 0.
2 MB
The command,  MB,   is used to enter a box or line segment shape.  
The command,  MB [l],  is used to modify an existing box with the tag
identifier l. After the MB command is used, the cross-hairs will appear
on the screen.  Position these at the first point of the box or line,
and type any character except C or E (the space bar is useful here). 
Re-position the cross-hairs to the next point and type another
character.  The first line segment will appear on the screen.  To
terminate entry, type E (end of shape), C (close box) or A (draw arrow
to point). If a C is typed, a line will be drawn between the current
point and the initial point of the box or shape. 
2 MC
 The command 
	MC n
 is used to modity the default character set (#3).  The command
	MC l n
 is used to modify the character set of an entry specific text
 string.  
2 MO
 The command 
	MO a
 is used to modify the default orientation of text. The command
	MO l a
 is used to modify the orientation of the specified text string.
 The initial default orientation is 0. degrees with respect
 to the X-axis.
 If the MO command is used with a box, the line type is changed.
 	0	straight line
2 MP
 The command
	MP l
 is used to modify the position of a string or box.
 When MP is used, the cross-hairs will become visible.  Position the
 crosshairs and type
 L	to use this point as the lower left-hand corner of the text
 R	to use this point as the lower right-hand corner of the text
 C	to use this point as the center point of the text
2 MS
 The command
	MS s
 is used to modify the default lettering size.  The command
	MS l s
 is used to modify the lettering size for the specific text string
 or box.  The size s is entered in floating point inches.  The 
 initial default lettering size is 0.25 inches.
2 MT
 The command
	MT l<text>
 is used to modify (replace) the text string specified by tag l.
 If MT l<cr> is used,  that string is eliminated and the tag identifier 
 released for re-use.
2 N
 The command
	N m
 is used to generate m tic marks along the right side of the graph
 when it ix next re-drawn.
2 R
 The R command is used to re-draw the graph with the latest 
 modifications and additions included.  The tic'ed axes are
 included, as well as the identifying tag letters associated with each
 string or figure.
2 S
The command
	S fnam
 is used to save the current set of TVG commands as a file.
 The extension >TVG is automatically appended to the file name if
 an extension is not specified.
 TVG does not update the version number of the file, so if you
 are planning to use both the unmodified and modified versions of
 a file, make a copy before entering TVG.  Once the file is saved,
 it may be recalled for modification by using the unsave command
	U fnam
2 U
 The command
	U fnam
 is used to read in a previously saved file of TVG commands.
 The extension .TVG is assumed if no extension is specified.
