Function IsSomething

IsSomething(v)

The function verifies if a variable has a non-null value, or has members, of array indexes. Example:

' it is null
a = null

' it has non-null value assigned
b = 1

' it is null, but has a member assigned
c = null
c.member = 2

' it is null, but has array index assigned
d = null
d[2] = "hello"

if IsSomething (a) ' not true
	print("a is something")
end if

if IsSomething (b) ' true
	print("b is something")
end if

if IsSomething (c) ' true
	print("c is something")
end if

if IsSomething (d) ' true
	print("d is something")
end if
