IndexValue(I)
Returns the index value for the given variable or index.
In Analytica, a variable may have both an index value and a result value. This may occur in a self-indexed array, in a variable or index defined as a list of identifiers or list of expressions, or in a Choice list with a self-domain, to list a few examples.
The IndexValue function gives you access to the index value from a value context.
Library
Details
The IndexValue function, if it weren't built-in, could easily be defined within Analytica 4.0 as:
Function IndexValue( I : IndexType ) := I
This definition, however, requires Analytica 4.0 or later.
Examples
Index L := [I,J,K,"value"] Index rows := 1..Size(A) Variable Flat_A := MdArrayToTable( A, rows, IndexValue(L) )
