C.ll.l. SYSTEM - Erase System Files only
Usually, $ERASE will affect visible files only. Files which have been
attached a SYSTEM attribute by means of
=>
$SET are not erased. Never-
theless, activating the "+SYSTEM" option will allow you to access all
such files,
C.ll.2. ALL - Erase all Files within a User Area.
Use the option "+ALL
11
to erase both normal and SYSTEM files.
C.ll.3. USERS - Erase Files in all User Areas.
The option "+USERS" enables you to extend the erasure process to all
user areas. You may combine this option with the options "+SYSTEM
11
and
"+ALL". In this case, $ERASE displays the user area instead of the drive
of the files erased:
ERASE *.COM +USERS
3 files found. Erase? (Y/N) Y
0:$DIR .COM
10 KB)
erased.
0:$SET .COM
8
KB) r/o not erased.
l:PROGRAMX.COM ( 20 KB) erased.
2 File(s) erased, 30 Kbytes released, 376 Kbytes remaining.
Here, the file "$DIR.COM" in user area
0
and the file "PROGRAMX.COM" in
user area l are erased.
C.ll.4. R/0 - Erase also Write Protected Files
In the previous examples we saw that write protected files are precluded
from being erased. If, however, you activate the "+R/0" option, write
protection is ignored when erasing
1
which could look like:
ERASE *.COM +R/0
3
files found. Erase? (Y/N) Y
A:$DIR .COM ( 10 KB) erased.
A:$SET .COM (
8
KB) r/o erased.
A:PROGRAMM.COM ( 20 KB) erased.
3 file(s) erased, 38 Kbytes released, 368 Kbytes remaining.
