15.64.58.1  Example  - 
     TD:SET TEXTURE DAASH
This generates a "hardware" texture or long dashes.
     TD:SET TEXTURE DOT DOT DASH
          or...
     TD:SET PATTERN DOT DOT DASH;  SET TEXTURE PATTERN
This  is  a  dot-dot-dash  texture,  which  is  also set to be the current
pattern.
     TD:SET TEXTURE DOT FUNNY DASH
          or...
     TD:SET PATTERN DOT RANDOM DASH;  SET TEXTURE PATTERN
This is a uniformly spaced dot 0.1" followed by a random length dash.
     TD:SET TEXTURE PATTERN DASH;  JOIN
          or...
     TD:SET PATTERN DASH;  SET TEXTURE PATTERN;  JOIN
Sets  the  texture  to  be  a  patterned  dash.   This will produce device
independent pictures, but they will be slower than:
     TD:SET TEXTURE DASH;  JOIN
          or...
     TD:JOIN DASH
