     ppxx - Pascal interpreter

     ppxx [_o_b_j [_a_r_g_u_m_e_n_t ...]]

DDEESSCCRRIIPPTTIIOONN
     PPxx interprets the abstract machine code generated by pi(1).  The first
     argument is the file to be interpreted, and defaults to _o_b_j; remaining
     arguments are available to the Pascal program using the built-ins _a_r_g_v
     and _a_r_g_c.	PPxx is also invoked by ppiixx when running `load and go'.

     If the program terminates abnormally an error message and a control flow
     backtrace are printed.  The number of statements executed and total exe-
     cution time are printed after normal termination.	The pp option of ppii
     suppresses all of this except the message indicating the cause of abnor-
     mal 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, Pas-
	   cal 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 ppxx
	   probably due to a Pascal system bug.

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