Can I not use constants in revserver scripts ?

[Alex Tweedly]

Thanks Mike - that's basically it.
Though in fact, it's even stranger than you said.

The dictionary says that if you set a constant in a script but outside 
any handler, then it can be used in any handler within the script; and 
that's exactly what it does do ...

> <?livecode
> constant K = "asdf"
> command doit
>   constant K1 = "qwer"
>   put "inside" && K && K1 & "<br>"
> end doit
>
> doit
> put "outside" && K && K1 & "<br>"
>
> ?>
  produces

inside asdf qwer
outside K K1

And that's pretty reasonable for a script in a stack (where you don't 
have "executable" statements outside any handler), but very unhelpful 
for revserver, where it is very common to have executable code "in-line" 
rather than in side a handler.

Oh well - I'll submit it as an enhancement request, and stop using 
'constant' for now.

Thanks
