C>DIR B:
B: BASIC
COM
c) List all the files with the same extension on any drive
Wildcards can be very useful when this is required. For example, to show all
the COM files on the current drive:
C>DIR *.COM
C : PIP
COM: STAT COM: SUBMIT COM: XSUB COM
C : CONFIG COM: FlUNK COM: TERM COM
C>DIR A: * .BAS
NO FILE
This message informs you that there are no files conforming to that name on
the A:· drive. The message will appear whenever you ask for a DIRectory of
a drive on which no files with the specified name reside.
C>DIR D:*.BAS
D : TEST BAS: DEMOl
BAS: DEM02
BAS
There may be other files on drive D: but as the request was only for those with
the extension BAS so they are the only ones listed.
d) Check that a particular file is on a particular drive
If you ask for a particular file by name it
wi~l
be displayed on the screen. If
it is not present the "NO FILE" message wIll be prmted.
For example:
A>DIR B:TEXTl.DAT
B:TEXTl.DAT
A>
shows the file is on disk B :
A>DIR B:TEXTl.DAT
NO FILE
A>
shows the file is not present.

e) List all the files with the same name on any drive
It
may be that there are files with the same name but different extensions on
the same drive, for instance assembler program files, so the asterisk wildcard
can again be used:
D>DIR START. *
D: START ASM: START HEX: START
PRN
C>DIR D:START.*
D: START ASM: START HEX: START PRN
f)
List all files with similar names on any drive
This is where you can really start to use the wildcards! For instance:
D>DIR S??????? *
will list all files on drive D: whose names begin with S of any extension;
D>DIR C: *
.cn
will list all the files on drive C: whose extension begins with C;
A>DIR D:DEM??BAS
will list all those files on drive D: whose names consist of five letters beginning
with DEM and whose extensions are BAS.
g) Microcassette Tape DIRectories
The Microcassette drive is always named drive H: and is used in the same way
as the other drives.
H>DIR
H: TEST.BAS
If the tape is mounted, the directory will be read from the directory stored in
memory, and so will be read immediately.
(
If the drive is unmounted when an access is made the drive will wind the tape
to the beginning and mount the tape. The directory is then stored in memory.
It
may take a short while for the tape to be mounted.
