Listing the Directory of a Disk

To list the directory of a disk, enter DIR followed by the drive number. BASIC-80 assumes drive 0 if you don't specify:

DIR
NAME.EXT	RECS	LENGTH	ATTR
ALPHA	31	3728
ATTRIB	38	4677
BASIC	178	22571
COpy	64	7967
DCOPY	32	3961
DELETE	37	4501
DIR	46	5728
DSORT	11	1264
EDIT .MAC	5	469
INDEX .I	46	5669
NED	79	469
RENAME	21	2438

Renaming a File

The RENAME command lets you change the name of any file from an old filename to a new filename. The directory listing also changes to the new filename. In the ex- ample below, file :FI:PROG changes to :FI:MYPROG:

RENAME ":F1 :PROG" to ":F1 :MYPROG"

Changing File Attributes

With the BASIC-80 ATTRIB command, you can protect a file from overwriting, deletion, or being renamed by setting the write-protect attribute "W" . If you set the invisibility attribute, "I", the file will not appear when the directory is listed. If you set the format attribute, "F", the file will copy to a disk formatted with the IDISK or FORMAT commands. The system attribute, "S", makes the specified file copy to a disk when the disk is formatted by the FORMAT command or copied with the COPY command.

For each attribute, the format is "XO" if the attribute is disabled, "Xl" if it is enabled, where X is either W, I, S, or F. The format of ATTRIB is:

ATTRIB "filename", "XO"I"X1"

Deleting a File

If you want to get rid of a file or program, you can use the KILL command to delete it and remove its listing from the directory. Once a file or program has been killed, it cannot be recovered. The format of the KILL command is KILL followed by the filename in quotation marks. For example, to delete a file named ANLYZ on the disk in drive 1, enter:

KILL ":F1 :ANLYZ"
