Good for you.

Leo's? Not mine? What's Leo's look like?

Where in the Startup message?

What's the point of this? Workbench will pass variable numbers of arguments,
and usually at least one (dirlock & name of the program itself).

More details, please.

You're copying the file handles? Interesting. I wouldn't have expected that to
work... I don't think there's any guarantee of that.

(too bad there's no DupFH call. Commodore? Are you there Commodore? How about
 for 1.4?)

Sounds good. Where's the code?

Why don't you do this?

	sprintf(PipeName, "%s:rogue%dpipe%d", PipeDevice, ProcessId, Sequence++);
	pin = Open(PipeName, MODE_NEWFILE);
	pout = Open(PipeName, MODE_OLDFILE);

This way you won't have to depend on anyone having PIP:, and won't be playing
unportable games...
