If there is just one program saved on your cassette, then you need not specify "filename." but if there is more than one. then you must specify "filename."
If there is a mismatch between the name you supplied to this command and the one on the cassette, then the message Skip "filename" will be displayed and the program you intend to load will not be loaded.
Note here that even the case (upper/lower) difference counts as a mismatch.
In case the program you intend wouldn't be loaded, push the reset key and repeat the entire process of the load once more.
If you have registered the count on the tape recorder counter, then spin the tape up to the place marked by the count and start loading from that place.
