Ah, yes multi-dimensional arrays are fully supported by LC. put "ABC" into myMDArray[ 1 ][ 3 ][ 2 ]
LC allows for nexting arrays, so basically this is an array of arrays of values, or a three dimensional array. ~ Chris Innanen ~ Nonsanity On Wed, Apr 27, 2011 at 3:20 PM, Pete <p...@mollysrevenge.com> wrote: > I think maybe I used the wrong term.
