I recently discovered that the DOS command "eval" has a problem,
specifically, "eval 4 mod 3" returns an answer of 0, rather than the 1
it should.
This did not occur on the 1.3 W/B, but does with the 1.3.2 (which
included a new eval), and 2.0 Beta 5.
Could those with newer versions of 2.0 (2.01, 2.02?) than 36.16 check
and mail me the result (and the version)?
I have mailed bugs@commodore, but not received a reply yet (one of
andy's items to me took a month to bounce!) so I can't be sure it got
through.

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.
