a variable is not defined - shouldn't a Quick Fix let me solve that easiyl?

It sounds like a stupid question to me, as I'm sure there must be an easy solution in Eclipse, I just couldn't find it out.

I have a line of code like this:

add 1 to gd_flying_monsters.

gd_flying_monsters is not defined yet, so it's a syntax error, ok.

Now I would have expected, that there's a Quick Fix (ctrl + 1) to create the definition (in SE80 I would just double-click), however, the only Quick-Fix option I’m offered, is renaming the variable.

This is how it looks like:
