Remarks

• Function statements. In the {$X+} mode, function calls can be used as procedure calls; that is, the result of a function call can be discarded, rather than passed to another function or used in an operation or assignment. Generally, the computations performed by a function are represented through its result, so discarding the result makes little sense. Sometimes, however, a function is called because it performs a task such as setting the value of a global variable, without producing a useful result.
• The Result variable. In the {$X+} mode, the predefined variable Result can be used within a function body to hold the function's return value.
• Null-terminated strings. In the {$X+} mode, Delphi strings can be assigned to zero-based character arrays (array[0..X] of Char), which are compatible with PChar types.
