setting path in command window using perl

[Amish Rughoonundon]

Hi,
here is my problem. I have a perl script that executes multiple
command line calls as follows:

system("XCOPY", "$s_currentWorkingDirectory\\KCPSM3.EXE",
$s_tempLocation, "/R", "/Y") == 0 or die "File KCPSM3.EXE could not be
copied: $!\n";
system("XCOPY", "$s_currentWorkingDirectory\\ROM_form.coe",
$s_tempLocation, "/R", "/Y") == 0 or die "File ROM_form.coe could not
be copied: $!\n";

This is an example. There are many more with different programs being
called.

My problem is that I need to set the path to a certain batch file
before calling the programs.

It seems everytime I call system though, perl open a command window,
executes the program and closes the window.

So even if I set the path at the beginning, once system is done
running, the path disappears.

Can I force perl to run everything into only 1 command window.

I hope I was clear with my question. Thanks a lot for the help,
Amish

No problem, just do so
$ENV{PATH} = .......

Of course. That is the semantic of system().

So even if I set the path at the beginning, once system is done
running, the path disappears.

Of course. Environment variables are never inherited from the child to
the parent.

Yes, you could. Just start all your external commands from the same DOS
command line:
system ("cmd1 & cmd2 & cmd3 & cmd4");
But why?

I {changed directory, modified my environment} in a perl script. How
come the
change disappeared when I exited the script? How do I get my changes
to be visible?
