(ii) The general rules for naming a data item can also apply in the case of the condition name.

(iii) If similar condition name is used in more than one place, the condition name should be qualified by the name of its conditional variable.

(iv) The name of the conditional variable can be used as the qualifier for any of its condition names. When the reference to a conditional variable needs qualification or subscripting, the similar combination of qualification or subscripting should also be used for the related condition name.

(vi) When the THRU/THROUGH phrase is used, literal - 1 should be less than literal - 2 and literal - 3 must be less than the literal- 4.

(vii) The conditional variable can be a group item or an elementary item. Though, it cannot be the other condition name, or a 66- level item or a group containing the JUSTIFY clause, or the SYNCHRONIZED clause or the USAGE clause other than DISPLAY.
