1    /CALLABLE_EDT

       /CALLABLE_EDT
       /CALLABLE_LSEDIT
       /CALLABLE_TPU
       /CALLABLE_TECO

    These qualifiers specify the callable editor that is invoked by
    subsequent EDIT commands. If you do not specify a qualifier, then
    the spawned command line is used to invoke the editor.

2    /START_POSITION

       /START_POSITION
       /NOSTART_POSITION

    Specifies whether to pass the number of the source line to the
    editor. /START_POSITION is appended to the command line that is
    also passed to the editor with each subsequent EDIT command.
    /NOSTART_POSITION is the default, unless spawned LSEDIT is
    selected. In that case, /START_POSITION is the default.
