Create and edit a file containing NCL commands, using language sensitive
 editing.  This requires the LSE editor to be installed and licensed.

       EDIT ncl-command-file-name

 The command file extension should be either COM or NCL to use the automatic
 LSE environment setup features.  You may also use the LSE command "SET
 LANGUAGE NCL" to set up the language environment.

 Syntax support is included for verbs, entities, attributes, arguments,
 and prepositional clauses.

 Menu support is included for frequently used verb, entity, attribute,
 argument, and preposition keywords.  This is limited to the keywords
 used with the NODE global entity.

 Some minimal semantic support is provided in that the keywords listed
 in a menu depend on the previous keywords selected.  If a keyword is
 entered manually, and is not selected from a menu, this semantic
 capability is lost.

 The initial placeholder used to start expanding a command is "{NCL_SCRIPT}".

 Example:  EDIT DECNET_SETUP.NCL
