Reading an article about Unix formatting and typesetting in
IEEE software (Sept 86), I stumbled on the following piece
of pic-code:

	.PS
	h = 2.0; y = 0.5; x = 0.5; n = 10;
	H: line right h
	L1: line up y from H.end
	L2: line down y from H.end
	for i = 0 to n do
	{
		line right x from i/n < L1.end, L2.end>
	}
	.PE

What's this? A cruel hoax? I've never seen for-loops in pic before
and they are certainly not defined in the grammar specification.
