- …variables.
- This feature, about the
   longest-running wish-list item ever, first missed the code cutoff
   for AutoCAD 1.4 in October 1989 and was finally implemented,
   eight years and eight AutoCAD releases later, in
   AutoCAD Release 12 as a MODEMACRO variable which allows
   DIESEL expressions.  In keeping with tradition, this feature was
   submitted on the day of the code cutoff for Release 12.
