function Status = zuiLoadFile()
% zuiLoadFile - Load a lens file into the ZEMAX DDE server, using Open File dialog.
%
% Usage : Status = zuiLoadFile
%
% Identical to zLoadFile, except that the filename is obtained from the user through a dialog box.
% Note that loading a file does not change the data displayed in the LDE;
% the server process has a separate copy of the lens data. The file name to be loaded is appended to the LoadFile
% item name, and must include the full path. For example: zLoadFile('C:\ZEMAX\SAMPLES\COOKE.ZMX'). The
% returned value is the same as for the zGetUpdate item; after updating the newly loaded lens file. If a value other
% than 0 is returned, the Update failed, if -999 is returned, the file could not be loaded. 
% Status of -998 is returned if the command times out.
%
% See also zGetPath, zSaveFile, zPushLens, zLoadFile
