The new EVAL gives the right results when I use "%" instead of "mod".  It
looks like Commodore needs to update the documentation.  Other observations:

eval ~ 0xf0		= -1	should be 0xffffff0f = -241
eval ~ -1		= -1	should be 0
eval 17 % 5		= 2	correct
eval 4 mod 3		= 0	should be 1
eval 4 foobar 3		= 4	should say "invalid OP"
eval 4 modx 3		= 3	"	"	"
eval 4 garbage 3	= -8	"	"	"
eval 12 xor 5		= 12	should be 9 (1100 xor 0101 = 1001)
eval 12 eqv 5		= -13	should be 6 (1100 eqv 0101 = 0110)
eval 12 & 5		= 4	correct
eval 12 | 5		= 13	correct

This is on an A3000.  C:EVAL $VER: 36.5 (18.4.90)
