localX var's

localX var's

[Mark Santcroos]

What's the diff between a "normal" variable and a LocalX variable?

I can see that they can't be referenced until they are initialized, so
there is at least one difference. :-)

Are they maybe "static" in their scope? (As in the C meaning of static)

Thanks

Mark

>From the spec:

"Up to 8 local objects can be referenced in a control method. On entry
to a control method, these objects are
uninitialized and cannot be used until some value or reference is stored
into the object. Once initialized,
these objects are preserved in the scope of execution for that control
method."

They're temporary scratch data objects, like C variables declared in
function scope, not like static C vars.
