I frequently use uigetfile. The drawback with uigetfile is that one can not choose a file that does not exist, ( which of course is the case the first time) e.i instead of a warning message I would like a message like "The file does not exist, would you like to create it? Yes No ". Does uigetfile exist in m-file format, so that I can enter this extra feature myself, or does a user contributed file exist that does the same thing? I would prefer Matlab4 code, since I have to work in the Matlab4 environment until RTW is Matlab5-compatible.
