This is not what is observed in CAS (or XCAS) ... perhaps a bug ?

HOME> true OR false AND false      → 1
CAS>    true OR false AND false      → false

It wouldn't be the first inconsistency between HOME and CAS environments!

The Xcas documentation doesn't seem to describe the precedence of operators in the Giac/Xcas language, but all the boolean operators are described in the same section, so I guess 'and', 'or', and 'xor' are evaluated at the same precedence in left-to-right order. Changing the compatibility mode doesn't seem to make a difference to the operator precedence.
