[Coco] Copying over an IO ERROR

[William Astle]

Also, the DIM statement on line 10 is not required. DECB will happily 
define any variable the first time it is encountered so predefining them 
with DIM is not needed.

Some experimentation shows that DIM with scalar variables does define 
the scalar variables, though, even though it's only documented for use 
in defining arrays. (At least I don't remember any official DECB type 
references indicating DIM with scalar variables.)
