If the program terminates abnormally an error message and a
control flow backtrace are printed.
The number of statements executed and total execution time
are printed after normal termination.

Most run-time error messages are self-explanatory.
Some of the more unusual ones are:
.It Reference to an inactive file
was used before a call to
.It Statement count limit exceeded
The limit of 500,000 executed statements
(which prevents excessive looping or recursion)
.It Bad data found on integer read
.It Bad data found on real read
Usually, non-numeric input was found for a number.
For reals, Pascal requires digits before and after the decimal
point so that numbers like `.1' or `21.' evoke the second diagnostic.
.It panic: Em Some message
Indicates an internal inconsistency detected in
probably due to a Pascal system bug.
Post-mortem traceback is not limited;
infinite recursion leads to almost infinite traceback.
