Thanks for all the replies,
I got this code from a protocol spec that I must use for communications to a
RS232 interface and this the way they calculate the CRC for the data in the
packet.
I have never done any C programming and thought that somebody in this list
may be able to assist.
The idea
Hi Chris,
that seems to be exactly what i need.

The time in used by the cpu for the execution of the script, rather
than the wall clock time.
CPU execution time for program = Clock Cycles for program x Clock
Cycle Time
But i'm interested in the cpu cycles used purely for the python app,
regardless of what other processes may be running.

What do you mean by cpu time, Kim?

I saw a snippet of python which is used to execute another python
script, and I'm trying to understand the mechanism. Simple as it is, I
don't understand how it works :-)
this is the caller
##
callee=open("tester.py").read()
exec(callee)
eval("main(['', 'argument'])")

I wonder if there's any way to wave this one under their nose. If for no
reason other than to stem potent

Hi all,
Is it possible to do self modifing script ? I think like variables which
are defined in the beginning of script could be modified by it self on
the run... like saving setting but not to external file but directly to
it self...
Thanks and best regards

When I try to use something like:

or:

First, you need to find the preprocessor define for CCITT_POLY. The code
is incomplete without it.
Second, where did this code come from? It defines an unused local named
cval, which will usually cause at least a compilation warning.
This looks like a snippet, not a complete CCITT CRC calculati

I suggest you Google "Python CRC" and find out how others have done
this, rather than trying to translate the code direc
