SMALL BASIC: Removing unwanted element

Hi, SMALL BASIC programmer, welcome.

In this tutorial, we will learned about removing unwanted element from an array, in this case from a single line multi colomn (SLMC) array not multi line multi colomn (MLMC). So, watch it.

For example, we want to remove element that have value FAILED from an SLMC array.

There are couples method that you can do to this, but I prefer this. If you do this differently, you will get different experience.

x[0] = "SUCCESS"
x[1] = "FAILED"
x[2] = "SUCCESS"
x[3] = "SUCCESS"

k = 0
m = 0
For i = 0 To 3
  If x[i] = "FAILED" Then
    x_l = Array.GetItemCount(x) - 1
    'Move the front and the back
    For j = i + 1 to x_l
      y[k] = x[j]
      k = k + 1
    EndFor
    For l = i - 1 To 0
      z[m] = x[l]
      m = m + 1
    EndFor
    'Merge y and z, merge y to the back of z
    '1st. Search the length of z
    z_l = Array.GetItemCount(z) - 1
    '2nd. And then transfer one by one
    For transfer_index = 0 To z_l
      y[Array.GetItemCount(y)] = z[transfer_index]
    EndFor
  EndIf
EndFor

TextWindow.WriteLine(y)
