hi. ok i used this:

INPUT "What file do you want to copy"; filepath$
dir$ = filepath$ + " C:\DOS"
SHELL dir$

Hi Brent; you're doing this backwards.  Lets say you enter "taco" for your filepath$.

Your dir$ will become taco C:\DOS, which isn't any kind of DOS command, (or any other.)

Your dir$ needs to be complete.  Lets say you want to end up with this:

COPY C:\taco.txt C:\DOS

Then you would need to do this:

INPUT "What file do you want to copy"; filepath$
(You enter "taco.txt")
dir$ = "COPY C:\" + filepath$ + " C:\DOS"
SHELL dir$

Try that.

Also, if you want to make sure the person entered a file extension, do this:

INPUT "What file do you want to copy"; filepath$
(You enter "taco") Leaving off the extension.
IF RIGHT$(filepath$,4)<>CHR$(46) THEN
 PRINT "You must enter a file extension."
 INPUT "What file do you want to copy"; filepath$
END IF
dir$ = "COPY C:\" + filepath$ + " C:\DOS"
SHELL dir$

There's lots of ways to do an error check, I just did that one real quick to fit into this forum.  Experiment with different techniques.

the difficult way to copy files within SHELL:

LET file1$ = "in.txt"
LET file2$ = "out.txt
OPEN file1$ for input as #1
OPEN file2$ for output as #1
DO UNTIL EOF(1)
LINE INPUT #1, dummy$
PRINT #2, dummy$
LOOP
CLOSE #1: CLOSE #2

the text in "in.txt" is now dito to "out.txt"
remember that in 1 program the max filenumber is #16
