                     15: .I Px
                     16: interprets the abstract machine code generated by
                     17: .I pi.
                     18: The first argument is the file to be interpreted, and defaults
                     19: to
                     20: .IR obj \|;
                     21: remaining arguments are available to the Pascal program using the

                     30: .PP
                     31: If the program terminates abnormally an error message and a 
                     32: control flow backtrace are printed.
                     33: The number of statements executed and total execution time
                     34: are printed after normal termination.
                     35: The

                     51: Most run-time error messages are self-explanatory.

                     59: .I output
                     60: was used before a call to
                     61: .I reset
                     62: or
                     63: .I rewrite.
                     64: .HP 6

                     66: .br
                     67: The limit of 500,000 executed statements
                     68: (which prevents excessive looping or recursion)

                     74: .HP 6
                     75: Bad data found on real read
                     76: .br
                     77: Usually, non-numeric input was found for a number.
                     78: For reals, Pascal requires digits before and after the decimal
                     79: point so that numbers like `.1' or `21.' evoke the second diagnostic.
                     80: .HP 6
                     81: panic:

                     92: Post-mortem traceback is not limited;
                     93: infinite recursion leads to almost infinite traceback.
