How to make an Array

An Array is a list in which different variables of the same datatype can be stored.
You can access each variable by its position in the list, the first variable has got the position number 0.

The Program

At start time an array of Strings is initialized and filled. If you click the button,
the variables of the array will be displayed.
First you have to add variables to the array with the function Array.Add().
If you have done this, you can access a variable: xyz = Array[x].
You can set a variable: Array[x] = xyz
(see also collections)

The Code:

arStr AS String[]

STATIC PUBLIC SUB Main()
  hForm AS Fmain
  hForm = NEW Fmain
  hForm.show
END

PUBLIC SUB _new()
  i AS Integer
  arStr = NEW String[]
'arStr = NEW String[5]
'does NOT work!
  FOR i = 0 TO 4
    arStr.Add(Str(i))
  NEXT
  arStr[3] = " hello"
END

PUBLIC SUB Button1_Click()
  i AS Integer
  txt AS String
  FOR i = 0 TO 4
    txt = txt & arStr[i]
  NEXT
  TextLabel1.Text = txt
END
