     _\bP_\bx interprets the abstract machine code generated by _\bp_\bi. The
     first argument is the file to be interpreted, and defaults
     to _\bo_\bb_\bj; remaining arguments are available to the Pascal pro-
     gram using the built-ins _\ba_\br_\bg_\bv and _\ba_\br_\bg_\bc. _\bP_\bx is also invoked
     by _\bp_\bi_\bx 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 p\bp option of _\bp_\bi 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 _\bi_\bn_\bp_\bu_\bt or _\bo_\bu_\bt_\bp_\bu_\bt was used before a
           call to _\br_\be_\bs_\be_\bt or _\br_\be_\bw_\br_\bi_\bt_\be.

     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: _\bS_\bo_\bm_\be _\bm_\be_\bs_\bs_\ba_\bg_\be
           Indicates an internal inconsistency detected in _\bp_\bx
           probably due to a Pascal system bug.

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