| Cell write | `Cells(1, 1).Value = a` | Done |
| Cell read | `x = Cells(1, 1).Value` | Done |
| Comment | `' comment` | Done |
| Application.Calculation | `Application.Calculation = xlCalculationAutomatic` | Done |
| Arithmetic expressions | `Cells(1, 1).Value = a + 1` | Done |
| For loop | `For i = 1 To N ... Next i` | Done |
| For loop (step) | `For i = 10 To 1 Step -2` | Done |
| If / Else | `If x > 0 Then ... Else ... End If` | Done |
| Single-line If | `If x > 0 Then y = 1 Else y = 2` | Done |
| Do While loop | `Do While x > 0 ... Loop` | Done |
