$R: Range-Checking Switch
Enables and disables the generation of range-checking code
Syntax: {$R+} or {$R-}
Default: {$R-}
Type: Local
Menu Command: Options|Compiler|Range-checking
The $R+ State
In the $R+ state,
- 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.
$R+ does not apply to Inc. and Dec.
Enabling range-checking slows down your program and makes it larger.
Use this option when debugging, then turn it off once the program is bug-free.
