Text to be written.If the text contains blanks, they must be enclosed in strings.
The text string may contain normal as well as special characters.

Specify the lower left corner of the text (in world coordinates).
If omitted, the position will be defined by the cursor

x- and y-position, respectively, relative to the coordinate origin.
At the origin (xr,yr)=(0,0), at the upper right corner (xr,yr)=(1,1).

Angle of text direction with respect to x-axis

Specifies a cursor prompting loop for the text position

Specifies the size of characters: size = rsize * UNIT * SCALING

Specify the size of characters in x- and y-units, respectively

Specify the position within the text string, given in units of the string length and height.

Defines the space between characters.

Linewidth of the letters relative to their height, for thick letters only.

Inclination of characters. Counterclockwise.

Length of characters. len > 1 causes a stretching.

Specifies the text colour. Possible choices are:
D for default (foreground) colour and colour compositions.

Draw a frame around the description and erase background before writing the description.
FRAME might also be given an argument, which describes 
colour and  hatching
of the frame area and the frame outline. 

Specifies clipping of text at the coordinate axes.
   clipmode = off : switch off clipping,
   clipmode = on  : switch  on clipping.

Specifies the line length (for text in formatting mode)
line length = rll * UNIT * SCALING

Specifies the line length (for text in formatting mode) in x-units * SCALING

Continue text in x-direction (for text in formatting mode)

Causes a line break (for text in formatting mode)

Specifies the spacing between current and next line (for text in formatting mode)

   fmt = on : switch  on formatting mode
   fmt = off: switch off formatting mode
In formatting mode if the input text lines do not fit on an output line
it is split at the spaces which separate the words.
Sometimes it will be necessary to split a word.
It is possible to give a prescription how to hyphenate a word.
It is a good idea to use some rarely used character to indicate the hyphenation positions.
Unfortunately the availability of such characters depends on the computer system.

























A good choice is the "`" character ("grave", ASCII hex 60). Example:

      un`pro`vi`ded




To support all cases the GMODE command
has an additional parameter to specify the hyphenation character:



      GMODE/HYPHEN(`)




A required blank is given by the character " "

In any case a break is excecuted automatically if the line begins with a blank.
A formatting example is shown in the tutorial.
 

" "                   required blank, not to be divided
`                     for dividing a word in formatting mode.

Subscripts, superscripts and overwrite:

2@0@8@Pb              208Pb, where "208" is a superscript
To$                   T0,    where "0" is a subscript
/#O                   O/,    on same place

Special characters like math and greek symbols 
are specified by a two character sequence followed by a ^:
