In Euphoria you could construct this as:

   sequence dataarray
   dataarray = repeat(repeat(repeat(repeat(0,3),4),6),3)

Note the reverse order: 3 4 6 3

You could then access individual elements with:
   dataarray[h][i][j][k]

In BASIC subscripts start at 0.
In Euphoria they start at 1.

In Euphoria you aren't limited to "rectangular"
shapes for your multi-dimensional arrays.
For example, each "row" of a 2-d array (sequence) could be
a different length. Also, in Euphoria you can grow or shrink
your multi-dimensional sequence along any dimension at any time
without having to discard all your data, like some Basics require
when you "redim".
