Commodore 1581 - Concat Command; Scratch Command

You will be asked as a precaution:
ARE YOU SURE?"
If you ARE sure, simply press Y and RETURN. If not, press RETURN
alone or type any other answer, and the command will be canceled.
The number of files that were scratched will be automatically
displayed. For example, if your diskette contains program files named
"TEST," "TRAIN," "TRUCK," and "TAIL," you may scratch all four,
along with any other files beginning with the letter "T," by using the
command:
SCRATCH "T*"
and if the four listed were the only files beginning with "T", you will
see:
01,FILES SCRATCHED,04,00
READY
The "04" tells you 4 files were scratched.
You can perform a SCRATCH within a program, but there will be
no prompt message displayed.
MORE ABOUT SCRATCH
SCRATCH is a powerful command and should be used with
caution to be sure you delete only the files you really want erased.
When using it with a pattern, we suggest you first use the same pattern
in a DIRECTORY command, to be sure exactly which files will be
deleted. That way you'll have no unpleasant surprises when you use
the same pattern in the SCRATCH command.
If you accidentally SCRATCH a file you shouldn't have, there is
still a chance of saving it by using the "Unscratch" program on your
Test/Demo diskette.
More about Splat Files
Never SCRATCH a splat file. These are files that show up in a
directory listing with an asterisk (*) just before the file type for an
entry. The asterisk (or splat) means that file was never properly closed,
and thus there is no valid chain of sector links for the SCRATCH
command to follow in erasing the file. If you SCRATCH such a file,
