$B: Boolean Evaluation Switch
Switches between the two different models of code generation for the AND and OR Boolean operators.
Syntax: {$B+} or {$B-}
Default: {$B-}
Type: Local
Menu Command: Options|Compiler|Boolean Evaluation
The $B+ State
In the $B+ state, the compiler generates code for complete boolean expression evaluation.
This means that 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.
The $B- State
In the $B- state, the compiler generates code for short-circuit boolean-expression evaluation.
This means evaluation stops as soon as the result of the entire expression becomes evident.
