This version of SAM76 brings you a very special treat when using the SAM76 language it is NOT NOT NOT NOT NOT necessary to worry about how you may move SAM files from one diskette to another, particularly if you only have one disk drive (like me). Merely flip the drive open after having brought into memory the desired file using the %bf,filename/ function, then remove the diskette, slide in a fresh one, close the door and execute the %uf,filename/ function - preceded of course by an %ef,filename/ function if file of same name on disk as evidenced by message {nav-uf-aef} telling you about an already existing file. .
