This group of functions enables various attributes for the handling of 
text to be manipulated. The following routines are available for this 
purpose:

 ∙ v_topbot          Sets text height
 ∙ vst_alignment     Sets horizontal and vertical alignment of a text
 ∙ vst_arbpt         Sets character cell height in points
 ∙ vst_arbpt32       Sets character cell height in points (fix31)
 ∙ vst_bg_color      Sets background colour
 ∙ vst_charmap       Selects character mapping mode (Atari/Bitstream)
 ∙ vst_color         Sets colour for text output
 ∙ vst_effects       Selects text effects
 ∙ vst_error         Sets the GDOS error handling
 ∙ vst_fg_color      Sets foreground colour
 ∙ vst_font          Selects face
 ∙ vst_height        Sets text size
 ∙ vst_kern          Sets kerning mode
 ∙ vst_map_mode      Selects character mapping mode 
                     (Atari/Bitstream/Unicode).
 ∙ vst_name          Finds and sets text face by name
 ∙ vst_point         Sets size of character cell
 ∙ vst_rotation      Sets rotation of text output
 ∙ vst_scratch       Designates size of the scratch buffer
 ∙ vst_setsize       Sets character cell width in points
 ∙ vst_setsize32     Sets character cell width in points (fix31)
 ∙ vst_skew          Sets angle of skew for skewed text ('italic')
 ∙ vst_track_offset  Sets offset for track kerning
 ∙ vst_width         Sets character width in pixels

The attributes set here are valid for a single workstation, and retain 
their validity until the program terminates, or the attributes are 
reset elsewhere.
