Dear FreePascal Community:
     When I implemented a program using Free Pascal, I got error
message run time error 201 as a result.  What does this mean, and
where can I get more information on error messages for Free Pascal?
Thank you.


                                            Best regards,
                                            Carl Mesaros

Error 201 is an ordinary range-check error.

Compile with range checks turned on and -gl and FPC normally shows you
a trace to the line producing that error. Or run your program using
lazarus and the debugger (also range checks turned on)

OP is posting duplicates here..
Note that range check errors are unique in that it takes programmer
interaction. They only appear when forced by {$rangechecks on} or
{$R+} otherwise they are ignored by the compiler. You won't see them
at all. But they are indicative of a problem with initialization, so
you must pay attention.
