Fortran95 expertise needed

[spacezebra]

Greetings all

I would like to touch base with someone who would be willing to review a very short program need to calculate some astro information about redshift and c/Ho.

Happy to pay for time, really just need to get over a stumbling block I have with the code.

Really need someone who is pretty switched on to this language, primarily I am flying blind on this one.

Cheers Petra

Hi Petra,

I could take a quick look.

No guarantees Petra - it's been about 30 years since I last programmed in Fortran, but it is the one and only proper language. Happy to have a look if you're still stuck.

Thank you so so much guys, what is the best way to send it to you?

Cheers Petra

If it is multiple source files, zip it into an archive and email to wildcard@wildcard-innovations.com.au

I'll take a look at it as well... if others are stumped. If it can't compile, then try https://www.lahey.com/check.htm (https://www.lahey.com/check.htm)

Why is it in FORTRAN and not a more modern language ?

Good question...answers range from...I like a challenge to... I have no idea.

I can think of half a dozen languages I’d prefer - starting with Xojo.

Hi Petra,

I've have sent you some emails but one salient issue was that you never
explicitly initialise the variable z.

I could get it to run and produce output by initialising z=0.0 otherwise
with GNU f95 compiler the executable never terminates.

The last item in the first line of output produces a floating point NaN.
There is a division the first time around where the denominator d_L
is zero or pretty nearly to it.

I added other recommendations in the emails.

Best Regards

Gary

Me too. Xojo is civilised. Especially the web server.
