Re: Windows environment error while trying to execute 16-bit application

Hi,

Thanks for your help.

I don't know before execution whether the target is going to be a DOS
program or not.

If I launch 32-bit programs and destroy cmd.exe / command.com then the
program itself doesn't exit, just the command `wrapper`.
