Enter F or f, (_^F to see ONLY the directory files via the FILE__MANAGER)

FILES allows the user to manipulate the files in the selected directory. 
Only non-directory files are shown.
.require "select_files.rnh"

If the user entered _^F a subset of the FILE MANGER functionality
is invoked. Only
the sub-directories are displayed. This option is included to allow the
user to obtain directory information for the sub-directories.

SWING reads the list of files in a directory by actually opening the 
directory file. This approach has been taken to improve the performance in 
situations where there may be many thousands of files in a directory.

SWING allows the use of the = key (EQUALS) to specify a search criteria for 
files in the file manager. This key may be used in both the directory manager 
and the file manager. When = is pressed SWING prompts for the search 
specification the response to which is a file specification (name.type) 
including wildcards as required. This specification becomes the basis of 
the search by the file manager when building up lists of files. This is 
similar to the DCL command DIR _*.C (for example).
.note
This 
operation may also be performed in the directory manager as an alternative 
to entering F or f to invoke the file manager.

e.g. of responses are _*.c, _*.h, _*.exe, test._* etc..
