		    TVG - TEKTRONIX VIEWGRAPH GENERATOR
 
 
TVG is an interactive program used to produce text-only viewgraphs.  Currently
it can only be used on the TEK 4014.
 
TVG is initiated by typing TVG in response to the MCR prompt:    >TVG  .
 
To obtain more information on TVG enter:   HELP TVG subqualifier

2 COMMANDS
 F/ollowing is a list of TVG commands:
 
  BYE          Logs you out of TVG, same as ^Z .
  CLEAR        Clears all text and box definitions; default value is unchanged.
  Et           Enter new text to be associated with the next avialable
	       identifier.  (No spaces between E and the first text character.)
  F [n]        Plot final viewgraph on TTn:.  Hit RETURN key to return to TVG
	       command mode.
  MA [l] d     Modify the alignment of textl to d, where d=R right justifies
	       textl, d=L left justifies textl and d=C center textl.
  MB l         Draw up to 32 connected line segments.
  MC [l] n     Modify the character set of textl to n.
  MO [l] d     Modify the orientation of textl to d degrees.
  MP l         Modify the position of textl to that of the crosshair input.
	       The alignment can be chosen by typing L, C or R to set point.
  MS [l] d     Modify the size of textl to d inches.
  MT l t       Replace textl with new text t.
  N n          Place n ticks on right side during REDRAW.
  R            Redraw with identifiers.
  S t          Save as file named t
  U t          Unsave (recall) from file named t.
 
2 DEFAULTS
			     TVG DEFAULTS
 
 TVG Assumes the following defaults:      MA = C   !  Centers Text
					  MC = 3   !  Simplex Roman
					  MO = 0.  !  Orientation is 0 degrees
					  MS = .25 !  Text size is .25 inches
 
 Note: On the commands MA, MC, MO and MS, if no textl is specified, the default
       value is changed for subsequent text entered.
 
       When using the save and unsave commands .TVG is the default file type.
2 COPY
  #SWITCHES
2 SWITCHES
 To generate a final viewgraph and copy, type:
 
	       >TVG filename.ext/switches
  or
	       >TVG @commandfile
 
 Where "filename.ext" is the name of the file in which the viewgraph
 description is saved, and "switches" are optional switches to control the
 output format of the final viewgraph.  Possible switches are are:
 
  /-FI         Suppress the filename identifier at the bottom right of the
	       viewgraph.
  /MG:n.nn     Specify magnification factor for the viewgraph.
  /TE:n        Specify final viewgraph output to terminal TTn: .
2 SUBCOMMANDS
 TVG Subcommands can be used to modify a text line.  They are preceded by a
 dollar sign ($) and inserted in the text line where the action is to take
 place.
 
 Following is a partial list of the subcommands available:
  D            Shift down to first level of subscript.
  E            Shift to exponent level.
  L            Shift down to second level subscript.
  M            Change to math character set.
  N            Shift to normal level.
  W            Change to script character set.
  X            Return to entry character set.
  n            Change to character set n=3,4,...,29.
  -            Underline between occurences, ("$-...$-").
  =            Double underline between occurences, ("$=...$=").
 
 For example:   E This $Wpart of the line is in script and $-underlined.
