Version 6.0 has been installed and tested at the University of Arizona
on a 3B5 without floating-point hardware.  The configuration information
and co-expression context switch were derived from those for the 3B20.

The 3B5 confguration should run on the 3B2 and 3B15, but these have not
been tested.

Bugs:

	Co-expressions work on simple cases, but in complex situations,
	memory faults have been encountered.

	Because of the way memory is allocated in System V, Icon may
	be unable to expand its memory region during program execution
	This problem can be circumvented by re-running the program
	and specifying larger region sizes via environment variables.

Notes:

	The -f flags given here for the Makefiles may cause warning
	messages on computers with floating-point hardware, but they
	should not affect the results of compilation.

Bottom line:

	This system is ready for installation.
