It looks like all variables have to be declared, for example:

for x = 1 to 10
    ? x
next

... is fine in VFP as there's no static typing. In X# VFP the closest you can get would be this, right?

for var x = 1 to 10
    ? x
next

Or you can just use a typical XBase style declaration:

local x
For x = 1 to 10
  ? x
endfor
// Alternatively
For Local x = 1 AS Int to 10

Alan,
If you enable 'Memvar' support and enable 'Undeclared memvar' support then this should work without any declarations, but I would not recommend that. It will produce code that is much less efficient
The least that you should do is declare them locally.
But it is much better to either declare the type yourself or use the VAR syntax and let the compiler determine the type.
