File dialog box

Many times I want to enter the name of a data file that is quite long. Typing it in is a pain, and the data files all have different names. A standard file dialog box would be nice. I believe it is available for the windows version? But I use a Mac. In a different fortran you got the standard file dialog box just be setting the file name to a null string in the Open statement. It was really nice.

Could you please add this feature to the Mac version?

Unless its available in some way I have not found, in which case: How do i do it?
