Chapter 41 You're The Boss - Tandy TRS-80 Owner Manual & Programming Manual

YOU'RE
THE
BOSS
Thanks
to
your
disk
filing
system, you
are able
to
command
the
Computer
to
do a
lot
of
very
helpful
things.
For example,
you can
rename
a
file. If
you've
taken your formatted
disk
out, re-insert
it.
Note: Can't
remember
if
your
disk's
formatted?
Check
the directory by typing DIB
(EBBS) (or
DIBB or
DIRi
if
you have more
than one
drive).
Type
this to
put a
file
on your
disk:
10
PRINT "THIS
IS
A
FILE"
(ENTER)
SAVE
"ORIGINAL/NAM"
(ENTER)
Check
the directory
to
see that the
program
file
is
stored
on your
disk
under
the
name
''ORIGINAL/
NAM"
. . .
Now
rename
it.
Type:
RENAME "ORIGINAL/NAM"
TO
"NEW/NAM"
(ENTER)
Hear
the disk drive
working? Check your DIRec-
tory again.
If
you'd
like,
LOAD
and
LIST
"NEW/
NAM." The program
file
has simply been renamed.
Everything
else
is
the
same.
RENAME
is
easy
to
use,
but there
is
one thing you
need
to
remember. Save
a
file
without an
exten-
sion
and
then
try to
rename
it.
Type:
13
PRINT "FILE
IE
"AFILE"
(E
JAME
"AFILE"
NUME
SER
TWO
BFILE"
'
(ENTER)
Sfli
NTER)
TO
'
rei* (ENTER)
The Computer
gives
you an
NE
error.
This
means
the
Computer
can't find
the
file.
When
you
RENAME
a
file,
you
must
type
in
the
complete
name
of the
file
so
that the
Computer
can
find
it.
This includes the
name
and
the extension.
As we
discussed
in
Chapter
2,
whenever you
SAVE
a
file
the
Computer
will
make
sure
it
has an
exten-
sion. If
you
don't assign
it
one,
the
Computer
will.
You
can check the
directory
to
find
out the exten-
sion of
"AFILE."
Then
RENAME
it.
Type:
RENAME "AFILE/BAS"
TO "BFILE/BAS"
(ENTER)
If
you're
renaming
a
program
file,
be sure
that
your
new
filename has
an
extension. In other
