6571 DY added (default is -10).

7057 This is a wrapper around the ShellExecute system function, which

7060 OPERATION is either nil or a string that names a supported operation.
7061 What operations can be used depends on the particular DOCUMENT and its
7062 handler application, but typically it is one of the following common
7065 \"open\" - open DOCUMENT, which could be a file, a directory, or an
7066 executable program. If it is an application, that
7067 application is launched in the current buffer's default
7068 directory. Otherwise, the application associated with
7069 DOCUMENT is launched in the buffer's default directory.
7070 \"print\" - print DOCUMENT, which must be a file
7071 \"explore\" - start the Windows Explorer on DOCUMENT
7072 \"edit\" - launch an editor and open DOCUMENT for editing; which
7073 editor is launched depends on the association for the
7075 \"find\" - initiate search starting from DOCUMENT which must specify
7077 nil - invoke the default OPERATION, or \"open\" if default is
7078 not defined or unavailable
7080 DOCUMENT is typically the name of a document file or a URL, but can
7081 also be a program executable to run, or a directory to open in the
7084 If DOCUMENT is a program executable, the optional third arg PARAMETERS
7085 can be a string containing command line parameters that will be passed
7086 to the program; otherwise, PARAMETERS should be nil or unspecified.
7088 Optional fourth argument SHOW-FLAG can be used to control how the
7089 application will be displayed when it is invoked. If SHOW-FLAG is nil
7090 or unspecified, the application is displayed normally, otherwise it is
