A named subset of values that a conditional variable may assume. The condition item is true when the conditional variable assumes any of the true values. The condition item is false when the conditional variable assumes any other value. A condition item may optionally specify a single preferred value for which the condition item is false when the conditional variable assumes that value. The declaration of a condition item includes a condition-name that is used to refer to the condition item.
In Relativity, a column may be defined on a condition item, in which case the column has a value of 0 for false, and 1 for true. Relativity also uses condition items for specifying null values, specifying filters, and binding subscripts. To help support these uses of condition items, the Relativity Designer allows definition of additional condition items that were not in the COBOL source program.
