passing information (arguments, commands, etc.) to another program using
"open process" requires that the other program has a mechanism to listen
to interprocess messages. Most programs designed to accept a set of
command-line parameters do not have listeners for inter process
communication (IPC), so the general answer to your question is you
probably can not provide arguments via open process to the copy command.

In a shell command I can execute a external program
using the following code:
on mouseUp
set the defaultFolder to desktop
put “myPic.jpg" into tFILE1
put “myPic copy.jpg" into tFILE2
put shell( "./copy" && quote & tFILE1 & quote && quote & tFILE2 & quote)
into pData
answer question pData —will be success or failed
end mouseUp
The code above will execute a program that has two arguments which are
the source file and destination file. It is a simple copy program.
I was reading about open process:
--open process appName [for [text|binary] {read | write | update | neither}]
I can open a process and execute the above mentioned external program
but I am not able to supply the arguments.
Is it possible using open process to execute a program with arguments
and if it is would it be better to use the shell command or open process?
I know if you use a shell command it takes control until it is done and
open process might run in the background which I do not really need
that I know of in this instance.
