Function to return the name of an active format file
FMT([<workarea | alias>])
The FMT() function returns the name of the currently active screen format file or a null string, if none is active. If the optional <workarea | alias> is specified, then the function will operate in the required workarea. The FMT() function always returns a character string in lower case including the file extension of the active format file.
If SET COMPATIBLE is set to FOXPRO or VFP the FMT() return value format differs in the following way: if SET FULLPATH is ON the full path to the format file is returned, if SET FILECASE is OFF then the return value is converted to upper case (Windows only).
