WMobile dos prompt or shell command

how to implement a dos prompt in Wmobile ?
scenario :

I have a button, when I click I want to execute the dos command "copy" , like : "copy invoice.prn COM4:"

I am using Windows Mobile 5.0 ,in my windows mobile 5.0 the command prompt can be open and when i type in the command prompt >copy invoice.prn COM4: , it will copy the file to the COM4, I want to put this command in a button? how to implement this?

Any advise please?

thanks

Mitchell,

Step one (don't know if this is realy needed....never had the need to use them):
Intall 1 out of 3 available tools, PPC Command Shell, PocketCMD or PocketDOS.

Step two:
Write your dos command to a BAT file and theirafter start this BAT file, e.g.:

   fSaveText("\MyFile.bat", "copy invoice.prn COM4:")
   ExeRun("\MyFile.bat")

thanks Merijin,
My problem has been solved....with the help of Mr. GOOGLE.

I used MortScript and I put the script inside the batch file. and I used shellexecute("test.mscr")

it works!

what is inside of my test.mscr file are only this line "Copy \Program Files\Soma\invoice.prn, COM4:,1"

it works perfectly!

no files or softwares to be installed...just only put MortScript on the registry...
