FORT\_WIDTH _ _ _ _ _ _ _ _ _ _ _ _ variable

The fort_width variable sets the number of characters in a line of Fortran-compatible output produced when the fort switch is on. Default is 70.

examples:

fort_width := 30; 

  FORT_WIDTH := 30  


on fort; 

df(sin(x**3*y),x); 

        ANS=3.*COS(X
       . **3*Y)*X**2*
       . Y

fort_widthincludes the usually blank characters at the be ginning of the card. As you may notice above, it is conservative and makes the lines even shorter than it was told.
