22、from U TIL ITIE S, the MA SS STORA GE menu group gives you access to the mass-storage file system controls. The system supports storage and retrieval of data files to and from floppy disk in either the DOS 1.44 MB or 720 kB format. Waverunner writes and reads all files to and from the floppy disk us

23、ing the current working directory. If the new file being stored bears the same name as an existing file on the same storage medium, the old file will be deleted. The default name of the working directory is L E CROY_1.DIR. This directory is automatically created when the media is formatted. If the m

24、edia is formatted elsewhere for instance on a PC the directory will be created the first time a file is saved to the floppy disk. The maximum number of files allowed in any one directory is 2400. You can change the name of the working directory to any valid DOS directory name, using the file- name p

25、references menu. A ll working directories are created as sub-directories from the root directory. A s in MS-DOS, the file name can contain up to eight characters followed by an extension of three characters. A file is treated as: a panel setup if its extension is PN L ; a waveform if its extension i

26、s a three- digit number; a waveform template if its extension is TPL ; a hard copy if its extension is TIF, BMP, or PRT; and HPGL if its extension is PL T.

30、n for manually stored files, and A tt.nnn for automatically stored files. The characters S and A represent the two storage methods. When automatically generating a file name, Waverunners system uses the assigned name plus a three-digit sequence number. If the assigned waveform name is already in the

31、 default Stt form (such as SC1, STB) the name will be changed to the A tt form: A C1, A TB and so on. A ll other user-assigned names remain as entered.

If you selectWrap, the oldest auto-stored waveform files will be deleted whenever the medium becomes full. The remaining auto-stored waveform files will be renamed the ol

33、dest group of files will be named “A xx.001”, the second oldest “A xx.002”, and so on.

35、e. The mass-storage file system indicates media size and storage availability in kbytes where 1 kbyte = 1024 bytes. Many media manufacturers specify the available storage in Mbytes where 1 Mbyte = 1 million bytes. This results in an apparent mismatch in specified versus actual media storage availabi

36、lity, when in fact the availability in bytes is identical. If the floppys write-protection switch has been pushed to the active position, Waverunner displays the message “Device is Write Protected” on the upper part of the grid whenever the medium is accessed for writing.
