EVALLIST Syntax: EVALLIST({list})

Evaluates the content of each element in a list and returns an evaluated list.

EXECON Syntax: EXECON(&expr, List1, [list2,…])

Creates a new list based on the elements in one or more lists by iteratively modifying each element according to an expression that contains the ampersand character (&).

Examples:

EXECON("&+1",{1,2,3}) returns {2,3,4}

Where the & is followed directly by a number, the position in the list is indicated. For example:

EXECON("&2–&1",{1, 4, 3, 5}" returns {3, –1, 2}

In the example above, &2 indicates the second element and &1 the first element in each pair of elements. The minus operator between them subtracts the first from the second in each pair until there are no more pairs. In this case (with just a single list), the numbers appended to & can only be from 1 to 9 inclusive.

EXECON can also operate on more than one list. For example:

EXECON("&1+&2",{1,2,3},{4,5,6}) returns {5,7,9}

In the example above, &1 indicates an element in the first list and &2 indicates the corresponding element in the
