)EDIT (type) name

APLX includes a 'full screen' editor for functions, operators, variables and classes. This editor may be accessed via:

             )EDIT

The editor is entered thus:

          )EDIT NAME          ⍝ EDIT EXISTING OBJECT <NAME>
                              ⍝ EDIT NEW FUNCTION OR OPERATOR <NAME>
          )EDIT 0 NAME        ⍝ EDIT NEW OR EXISTING FUNCTION OR OPERATOR <NAME>
          )EDIT 1 NAME        ⍝ EDIT NEW OR EXISTING VAR <NAME>
          )EDIT 2 NAME        ⍝ EDIT NEW OR EXISTING CLASS <NAME>

)EDIT can also be used to edit individual class members, rather than the whole class. In this case, you specify the fully-qualified name in the form ClassName.MemberName.
