NAME
pix - Pascal interpreter and executor SYNOPSIS
pix [ -blnpstuwz ] [ -i name ... ] name.p [ argument ... ] DESCRIPTION
Pix is a `load and go' version of Pascal which combines the functions of the interpreter code translator pi and the executor px. It uses pi to translate the program in the file name.p and, if there were no fatal errors during translation, causes the resulting interpreter code to be executed by px with the specified arguments. A temporary file is used for the object code; the file obj is neither created nor destroyed. FILES

NAME
px - Pascal interpreter SYNOPSIS
px [ obj [ argument ... ] ] DESCRIPTION
Px interprets the abstract machine code generated by pi. The first argument is the file to be interpreted, and defaults to obj; remaining arguments are available to the Pascal program using the built-ins argv and argc. Px is also invoked by pix 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 execution time are printed after normal termination. The p option of pi suppresses all of this except the message indicating the cause of abnormal termination. FILES
obj default object file pmon.out profile data file SEE ALSO
Berkeley Pascal User's Manual pi(1), pix(1) DIAGNOSTICS
Most run-time error messages are self-explanatory. Some of the more unusual ones are: Reference to an inactive file A file other than input or output was used before a call to reset or rewrite. 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 num- bers like `.1' or `21.' evoke the second diagnostic. panic: Some message Indicates a internal inconsistency detected in px probably due to a Pascal system bug. Charles B. Haley, William N. Joy, and Ken Thompson BUGS
Calls to the procedures dispose and linelimit are ignored. Post-mortem traceback is not limited; infinite recursion leads to almost infinite traceback. Because interrupts sometimes find the system in the middle of a procedure or function entry or exit, the error backtrace on an interrupt is occasionally meaningless. The current line is, however, always correct; only the call backtrace and the name of the current routine may be lost. 3rd Berkeley Distribution PX(1)
