IndexValue

IndexValue(I)

Returns the index value for the given variable or index «I». Some variables have both an index value and a result value. Examples include -- a self-indexed array; a variable or index defined as a list of identifiers or list of expressions; and a Choice list with a self-domain. IndexValue(I) returns the index value of «I», where (I) alone would return its result value.
