    552551The ©for©/©while©/©do-while© loop-control allows empty or simplified ranges.
     
    557556the down-to range ©-~=©\index{-~=@©-~=©} means inclusive range [N,M].
    558557©0© is the implicit start value;
    559 ©1© is the implicit increment value for an up-to range and ©-1© for an implicit down-to range.
     558©1© is the implicit increment value.
     559The up-to range uses ©+=© for increment;
     560the down-to range uses ©-=© for decrement.
    560561The loop index is polymorphic in the type of the start value or comparison value when start is implicitly ©0©.
