	lightgrey
class	key	lightgrey

ENTER

catalogues all files (in the current directory)

fred* catalogues all files beginning with fred

*.bas catalogues all files with a bas extension

Each file will be listed as:

File name	Creation time & date		Last updated time & date		Size
`letter.txt`	`Today`	`17:42:54`	`Today`	`17:42:54`	`1254`
`novel.txt`	`01-Jun-1987`	`17:41:17`	`Today`	`14:32:58`	`13112`
`game.bas`	`02-Jun-1987`	`12:27:43`	`02-Jun-1987`	`12:27:43`	`827`

* in characters.

(The last updated time and date are only relevant if OPENUP is used from BASIC.) If the file is open at the time it is catalogued, the size will not be shown.

When you catalogue or save to a blank EPROM, the display will go blank for a few seconds while the EPROM is checked.

CE

Catalogue EPROM

Gives a list of information on all files in an EPROM card fitted in slot 3. The directories and file names will be given to show where the files originally came from.

ES

Save to EPROM

Copies files from the filing system to an EPROM card fitted in slot 3. The file or files to be saved can either be selected as already described, or specified after the prompt

Name :

Note that while a file is being saved to EPROM the screen will blank intermittently until saving is completed, when the Cambridge Z88 will bleep.

EF

Fetch from EPROM

Copies files from EPROM card in slot 3 back to the filing system. Gives the prompts

Source : Destination :

Source: specifies the name of the file in the EPROM.

Destination: gives the name it is to be saved as in the destination filing system. It is initially set to the same as the source name, but you can edit it if you want to save the file under a different name.

CO

Copy

Makes a second copy of a file. Gives the prompt

Name :

allowing you to specify the file name to be copied, followed by the prompt

New name :

for the name of the copy.

Multiple files (selected in the catalogue window) can be merged into a single file with the Copy command; they will be appended in the order in which they were selected.

RE

Rename

Allows the name of a file to be altered. Gives the prompts

Name : New name :

For example, to change the name of a file from game.bas to 0ldversion you would specify

Name : game.bas New name : oldversion

Note that you cannot use the Rename command to move a file from one directory or device to another. The new name must be a simple file name; devices and path names are not permitted.

ER

Erase

Allows one or more files to be removed from the filing system. Gives the prompt

Name :

followed by the prompt

Confirm each file ? Yes

Pressing

Highlight

	lightgrey
	lightgrey
class	keylightgrey

ENTER

will prompt for each file you have selected to be erased, so allowing you to change your decision for any particular file. Alternatively, changing the option to No by typing N will erase all the selected files without further prompting.

You will not be permitted to erase a file which is in use; for example, a directory containing other files, or an open BASIC file.

Files can only be erased from the EPROM with the ultra-violet EPROM eraser.

Note that because parts of an erased file may still be present, you should not rely on the Erase command for disposing of confidential information from the system.
