(41) HP-16C+ - 16X=0? issue

[Ángel Martin]

Lines 02 - 05 in the TST program set the word size to 2, why is that intended??

Testing manually X<0? and X<=0? on 1CMP with 16x = -0d returns the correct "YES" result, not sure why your program doesn't get the same outcome... will need to look at it with more time.

But X=0? returns "NO", which I believe it is correct because -0d is not the same as 0d

in binary, 1CMP representation with WS = 2 :
00 = 11 ?? Not quite, so I'll stick by the current "NO"

isn't that right?
