3.6.7 Correcting Typing Errors

It is easy to correct typing errors in LOGO!:
If you have not yet concluded input, you can use ESC
to go back a step.
If you have already concluded input, simply start again,
as follows:
1. Move the cursor to the location of the error.
2. Switch to input mode: OK
3. Enter the correct wiring for the input.
You can only replace one block with another if the new
block has exactly the same number of inputs as the old
one. However, you can delete the old block and insert a
new one. You can insert whichever block you like.
