RTFM ;)

The *local* scope contains variables which only exist during the
invocation of the current function, object or apply statement. *Local*
variables can be declared using the var keyword:
function multiply(a, b) {
var temp = a * b
return temp
}
Each time the multiply function is invoked a new temp variable is used
which is in no way related to previous invocations of the function.
When setting a variable which has not previously been declared as local
using the var keyword the *this* scope is used.
The *this* scope refers to the current object which the function or
object/apply statement operates on.
object Host "localhost" {
check_interval = 5m
}
In this example the this scope refers to the *localhost* object. The
check_interval attribute is set for this particular host.
You can explicitly access the *this* scope using the this keyword:
object Host "localhost" {
var check_interval = 5m
/* This explicitly specifies that the attribute should be set
* for the host, if we had omitted `this.` the (poorly named)
* local variable `check_interval` would have been modified
instead.
*/
this.check_interval = 1m
}
Similarly the keywords *locals* and *globals* are available to access
the local and global scope. <----------------------------- !!!!!
