INCLUDE 'iolib.h' telling(FileName)
string(FileName) (i) Name of the file that is open
Returns the filename of the file that was opened with tell
(). If no file was opened, 'stdout' is returned.
NOTE: You should not mix up the old fashioned tell(), telling(), told predicates with the writedevice (), closefile (), or gotowindow () predicates. Always close files with the predicates belonging to the same family!
No runtime errors.
