Comments

  1. This keyword maps to /SKEW/FIX when Iflag = 0.
  2. This keyword maps to /SKEW/MOV when Iflag = 1.
  3. The option “_TITLE” can be added to the end of this keyword. When “_TITLE” is included, an extra 80 characters long line is added after the keyword input line which allows an entity title to be defined.
