* In the code below, I don't follow the usual method of *
* passing each command string in turn to Execute. Instead *
* I pass the entire command file as the new input stream, *
* which Execute accepts after processing the null string *
* it gets as a "command". This avoids the system having *
* to reload the DOS "RUN" module for every line of the *
* command file, though on the other hand it does lock out *
* the possibility of redirecting keyboard input through *
* the "current window" to the command. I thought the *
