Uses repetative conditionals that would be better formatted in a list:

If a named object is being executed the existing value will continue to be used until its execution is completed. However, the name becomes available immediately for other use.

Examples
)SI #.FOO[1]* ⎕VR'FOO' ∇ R←FOO
[1] R←10 ∇ +⎕EX'FOO' 1 )SI #.FOO[1]* ∇FOO[⎕]
defn error FOO←1 2 3 →⎕LC 10 FOO 1 2 3

If a named object is an external variable, the external array is disassociated from the name:

  ⎕XT'F' FILES/COSTS       ⎕EX'F' ⋄ ⎕XT'F'

If the named object is a GUI object, the object and all its children are deleted and removed from the screen. The expression ⎕EX'.' deletes all GUI objects owned by the current thread in the Root namespace but not those in sub-namespaces. In addition, if this expression is executed by thread 0, it resets all the properties of '.' to their default values. Furthermore, any unprocessed events in the event queue are discarded.

If the named object is a shared variable, the variable is retracted.

If the named object is the last remaining external function of an auxiliary process, the AP is terminated.

If the named object is the last reference into a dynamic link library, the DLL is freed.
