#### 37.4.1 Understanding list-variable syntax

To create a list variable, all you have to do is use a DITA2Go macro variable name with an index value in brackets, similar to C-language array notation:

$$listname[index]

For example:

$$mylist[$$_count] a variable as the index
$$mylist[2] a constant as the index
$$mylist[($$myindex + 1)] an expression as the index

List indexes can be nested

The index is a string, not just a number, so it can be anything, even another nested list reference:

<$$mylist[$$another[one]]>

You can access the number of items in the list with <$$mylist[]>.
