So you have written your program, finished testing it, and now you are ready to distribute it. You probably can't depend on the users of your program having Irie Pascal installed on their computers, so you will need to distribute the IVM Interpreter (i.e. the file ivm.exe) in addition to the executable file containing your program. If you have purchased a license to use Irie Pascal, then you may have the right to distribute the files necessary to run your programs (see the license agreement for details).
