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.

Details

The IndexValue function, if it weren't built-in, could easily be defined as:

Function IndexValue(I: IndexType) := I

Examples

Index L := [I, J, K, "value"]

Index rows := 1..Size(A)

Variable Flat_A := MdArrayToTable(A, rows, IndexValue(L))
