IndexValue

What's new in Analytica 4.0? >

(new to Analyica 4.0, requires build 4.0.0.33 or later)

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 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) )
