#DIM declare the variable and it's Data Type at COMPILE TIME.

`SET`	`#DIM`

No Data Type Declaration.	Enables IDE auto-completion.
Runtime	Useful for Object references.

#DIM name As %String
Set name = "Micheal Scott"
#DIM age As %Numeric
Set age = 36
#DIM employer As App.Employer               ; compile time
Set employer = ##class(App.Employer).%New() ; runtime
