Runtime error 201 means range check error. Quick glance over the source code makes me suspect that somewhere some operation returns a value that doens't fit in integer range (-32786..32767 in FreePascal by default). Easiest solution would be to use a larger datatype for example longint (roughly between -2*10^9..2*10^9) or int64 (~9*10^18..9*10^18).

If you use command line compiler using -gl command line option would display line numbers in run-time error backtraces. This would make it easier for you to pinpoint the issue.
