That I don't know.

Several options come to mind:

• Implement the required functions in Perl so I don't have to call a bunch of other executables
• Run each command separately (system, backticks or whatever), reading output back into perl, then present the output as appropriate, rather than trying to manage a bunch of separate command windows and processes running cmd.exe
• Compose a batch file then run it
• Try to establish a pipe to STDIN of cmd.exe and feed it commands, but then probably need something like IPC3::Open and Expect (but maybe not Expect itself on Windows - I don't know if it works there) and it quickly gets more complicated.

Having a *nix background, I don't much like the Windows way of doing process management. I find they make simple things, like process management and IPC very hard to do. For example, I still haven't found a simple way to get unbuffered I/O between a parent process and its child, or do anything like what process groups make easy on *nix. Being lazy, I do my best to avoid such issues. But this is my fault - probably not something you should emulate.
