I didn't redefine them because I didn't need them. But that makes me
think of the speed penalty.  It could be noticeable in some
applications.

Anyway, since the problem is the first fetch fails if the variable has
not been initialized, it seems better to initialize it by default than
to check every time if it has been initialized or not.  Besides, Gforth
initializes ordinary variables.

I think something like this could be a simpler and better alternative:

  : $variable  ( "name" -- )
    variable  pad 0 latestxt execute $!
    ;

Beside, it makes the definitions more legible.

What do you think?
