Folks,
I am getting the error
"Argument X is not a NUMBER: |GAIA_DISTRIBUTION/CON.63|."
When running some LISP code under CMUCL. Below is the full output. I
assume this is probably some basic LISP problem that, being new to this
language, I do not understand. Any idea on what may be causing this
problem? CON.63 is an image file.
Thanks,
Jim

I'm sure some of the guys will come up with the right answer, but in the
lisp (not cmucl) we run we can not mix integer and floats that is if our
functions expect floats we would have to write..
(run-gaia 0.69 32.0 500.0)
as opposed to
(run-gaia 0.60 32 500)
not sure if this is your problem. Some of these guys will know for sure.
In our endevaors this is a blessing for example if function "power" would
only accept integer arguments and automatically truncated its arguments
without a warning..... example
(power 1.9 4.9)
would really give ya the answer for
(power 1 4)...not good a lot!
forewarning is like foreplay
result are better in the end :) hee hee (sorry)

Well, |GAIA_DISTRIBUTION/CON.63| is a symbol, not a number. So the error
message is correct.

Instead of hitting ^C, try gettting a backtrace by entering :back. Then you
can see what code made up the symbol |GAIA_DISTRIBUTION/CON.63| and why it's
trying to subtract 131 from it.

Hmmm. This looks almost as if some part of the code were trying to do
arithmetic on something like a version number -- only to have someone
else (presumably) substitute a symbol for what used to be a version
number.
