SET DEFAULT (or... MOVING AROUND A VAX):
|
||
|
|
=======================================
|
||
|
|
|
||
|
|
To move around the VAX DCL, in and out of directories, I need
|
||
|
|
to tell you about the SET DEFAULT command. It is just like the
|
||
|
|
CD command on UNIX and MS-DOS/PC-DOS, except it follows a format.
|
||
|
|
The format is "SET DEFAULT [.subdir]" to go down to a sub direc-
|
||
|
|
tory and "SET DEFAULT [-]" to go to the parent directory. I will
|
||
|
|
explain more involved uses like changing disks, if asked, to keep
|
||
|
|
you out of trouble for now. First, I will show by example and
|
||
|
|
then explain my example to those out there who lack a brain.
|
||
|
|
|
||
|
|
$ DIR (step 1)
|
||
|
|
PROGRAM.EXE;2 PROGRAM.EXE;1
|
||
|
|
$ CREATE/DIR example (step 2)
|
||
|
|
$ DIR (step 3)
|
||
|
|
EXAMPLE.DIR;1 PROGRAM.EXE;2 PROGRAM.EXE;1
|
||
|
|
$ SET DEFAULT [.example] (step 4)
|
||
|
|
$ DIR (step 5)
|
||
|
|
no files, animals, vegetables, nor minerals error
|
||
|
|
$ SET DEF [-] (step 6)
|
||
|
|
$ COPY PROGRAM.EXE;2 [.example] (step 7)
|
||
|
|
$ SET DEF [.example] (step 8)
|
||
|
|
$ DIR (step 9)
|
||
|
|
PROGRAM.EXE;2
|
||
|
|
$
|
||
|
|
|
||
|
|
Here's what I did...
|
||
|
|
|
||
|
|
STEP 1: I asked to see the contents of the current directory.
|
||
|
|
I found that I have the program PROGRAM.EXE is the
|
||
|
|
1st and 2st versions in the directory.
|
||
|
|
|
||
|
|
STEP 2: I created a directory called "EXAMPLE." This name
|
||
|
|
can be anything of course.
|
||
|
|
|
||
|
|
STEP 3: I again asked for the contents of the directory. It
|
||
|
|
now shows me that I have a "file" called
|
||
|
|
"EXAMPLE.DIR;1." That is just the directory. Any-
|
||
|
|
thing with an extension of "DIR" will be a directory.
|
||
|
|
For more on extensions, see below.
|
||
|
|
|
||
|
|
STEP 4: I changed directories by use of the SET DEFAULT
|
||
|
|
command. You must always follow this format to
|
||
|
|
change into a SUB directory.
|
||
|
|
|
||
|
|
STEP 5: I AGAIN (!) looked into the directory. This time, my
|
||
|
|
directory was EXAMPLE so I of course saw nothing.
|
||
|
|
You will get an error I believe when you try to DIR
|
||
|
|
an empty directory.
|
||
|
|
|
||
|
|
STEP 6: This command is used to rise up to the parent direc-
|
||
|
|
tory. The parent directory contains the filename
|
||
|
|
"EXAMPLE.DIR;1," remember? The DEFAULT option can be
|
||
|
|
shortened to DEF.
|
||
|
|
|
||
|
|
STEP 7: Here I am illustrating how to move programs around a
|
||
|
|
little. I just copied the program PROGRAM.EXE;2 into
|
||
|
|
the subdirectory EXAMPLE.
|
||
|
|
|
||
|
|
STEP 8: See step 3. (a lazy, tired Dave)
|
||
|
|
|
||
|
|
STEP 9: I >ONCE MORE< issued the DIR command to reveal the
|
||
|
|
contents of the directory. I now find the program
|
||
|
|
PROGRAM.EXE;2 in my directory listing of my sub
|
||
|
|
directory EXAMPLE.
|
||
|
|
|
||
|
|
If you don't understand the basics of moving around a VAX by
|
||
|
|
now, push "OFF".
