ppxx [ obj [ argument ... ] ]
DDEESSCCRRIIPPTTIIOONN
_P_x interprets the abstract machine code generated by _p_i. The
first argument is the file to be interpreted, and defaults
to _o_b_j; remaining arguments are available to the Pascal pro-
gram using the built-ins _a_r_g_v and _a_r_g_c. _P_x is also invoked
by _p_i_x when running `load and go'.
If the program terminates abnormally an error message and a
control flow backtrace are printed. The number of state-
ments executed and total execution time are printed after
normal termination. The pp option of _p_i suppresses all of
this except the message indicating the cause of abnormal
termination.

Most run-time error messages are self-explanatory. Some of
the more unusual ones are:
Reference to an inactive file
A file other than _i_n_p_u_t or _o_u_t_p_u_t was used before a
call to _r_e_s_e_t or _r_e_w_r_i_t_e.
Statement count limit exceeded
The limit of 500,000 executed statements (which
prevents excessive looping or recursion) has been
exceeded.
Bad data found on integer read
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.
panic: _S_o_m_e _m_e_s_s_a_g_e
Indicates an internal inconsistency detected in _p_x
probably due to a Pascal system bug.

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