Switches on/off the two different models of code generation for the AND
and OR Boolean operators.
Syntax:
{$B+} or {$B-}
Default:
{$B-}
Remarks:
If {$B+} defined, the compiler generates code for complete boolean expression
evaluation. I.e. every operand of a boolean expression built from the AND and
OR operators is guaranteed to be evaluated, even when the result of the entire
expression is already known.
If {$B-} defined, the compiler generates code for short-circuit
boolean-expression evaluation. I.e. evaluation stops as soon as the result
of the entire expression becomes evident.
