[Axapta-Knowledge-Village] array problem in X++ coding - axapta (Adrsh Gupta)

can any body tell me about this array concepts::::--------

// A dynamic array of dates, with only 10 elements in memory

date d[,10]; (what it means)

// A fixed length array of NoYes, with 100 elements and 10 in memory

NoYes e[100,10]; (what it means)

-----------------------------------------------------------------------------------------------------

multiple array indicies:--------

real earnings[10*3];

When you wish to refer to earnings[i,j], you simply write

earnings[(i-1)*3 +j].

You can easily wrap this into a macro:

#localmacro.earningIndex

(%1-1)*3+%2

#endmacro

so you could write

earnings[#earningIndex(i,j)]

The above scheme may easily be extended to any number of dimensions. The element a[i1, i2, ..., ik] can be accesses by computing the offset

(i1 - 1)*d2*d3*..*dk +

(i2 - 1)*d3*d4*...*dk + .... +

(ik-1 -1)*dk +

(ik-1)

into an array containing (d1*d2*...*dk) elements

can any body tell me whats going on here.......
