File name of currently running code


p = mfilename('fullpath')
c = mfilename('class')


mfilename returns a string containing the file name of the file in which the function call occurs. When called from within the file, it returns the name of that file. This allows a script or function to determine its name.

p = mfilename('fullpath') returns the full path and name of the file in which the call occurs, not including the filename extension.

c = mfilename('class') in a method, returns the class of the method, not including the leading @ sign. If called from a nonmethod, it yields the empty string.
