Comment continue the code sur the next line dans VBA

[ForumBot]

I would like to type the mathematical forumla in VBA code which many lines. I would like to split it into many lines. How do I do it?

For example:

U_matrix(i, j, n + 1) = k * b_xyt(xi, yi, tn) / (4 * hx * hy) * U_matrix(i + 1, j + 1, n) + (k * (a_xyt(xi, yi, tn) / hx ^ 2 + d_xyt(xi, yi, tn) / (2 * hx)))

is very long. would like to split it.

Tried this:

U_matrix(i, j, n + 1) = k * b_xyt(xi, yi, tn) / (4 * hx * hy) * U_matrix(i + 1, j + 1, n) 
_+ (k * (a_xyt(xi, yi, tn) / hx ^ 2 + d_xyt(xi, yi, tn) / (2 * hx)))

But not working.. Need some guidance on this..

To have newline in code you use _

Example:

Dim a As Integer
a = 500 _
  + 80 _
  + 90

MsgBox a
