Enables and disables the generation of range-checking code.
Syntax:
{$R+} or {$R-}
Default:
{$R-}
Remarks:
The $R switch is usually used in conjunction with the $Q switch.
If {$R+} defined, all array and string-indexing expressions are verified as
being within the defined bounds all assignments to scalar and subrange
variables are checked to be within range.
If a range-check fails, the program terminates and displays a run-time error
message.
Enabling range-checking slows down your program and makes it larger. We
recommend to use {$R+} only for debugging purposes.
Keep in mind that range-checking mode affects even on “+“,
“*“ and Shl operators.
