MAX_ARG		The maximum number of arguments the UniVerse command language
		can parse on a single command line.

MAX_LONGNAME	Maximum length of a type 1 item name before a call to
		"eftoif".  This number is a KLUDGE to guessitimate the
		maximum lentgth allowed by UNIX.  It is approximately
		1/2 of the limit allowed by UNIX.

MAX_PATH	Maximum length of a UNIX pathname.

MAX_INPUT_SZ	Maximum number of characters returned by the input() function.

SIZEOF_SCRATCH	The size that newly created scratch buffers Are to be created.
		Since the input() function makes frequent requests for scratch
		buffers of size MAX_INPUT_SZ, SCRATCHSIZ should be greater then
		or equal to MAX_INPUT_SZ for maximum efficiency.
