That should produce the same result as before (plus gales of laughter from the bleachers). Expected. Python code isn't my forte obviously. :) Just to be sure is it a simple typo f1oat with a one instead of float with an ell? That it was, now renamed. And now that I know it works albeit in a separate window, I will now go back to the original syntax just to check, but no, the additional , shell=True without the double-quotes, inside the parens is still needed.

Gene, In an earlier email in this thread I lied when I stated the name of the file you were missing (I retyped what I thought I saw rather than copy+pasting). Tim Chase caught what is most likely your immediate problem: a digit one rather the letter ell in the filename. Where that filename came from is where you should be looking, imho. That will be called to the attention of the wiki submitter. I doubt if its that important as long as its consistent though. Thank you.

That is exactly what I see using Monospace font where the letter and digit are different shapes. And I see exactly that in firefox. That l is indeed a 1. No wonder I couldn't type it, but could copy/paste it. Until I renamed it with an l. That bit of confusion first bit me hard, darned near 30 tears ago, building a trig functions library for the Microware C compiler running on a trs-80 Color Computer. Source published in the Rainbow magazine, Offset plates made from a DMP printer. I don't remember that fondly at all. I traded printers because of that, the 9 pin DMP's used exactly the same image for both. I had quite a bit more gray hair when that was done. :( Thanks for making me go look again. :) Cheers, Gene -- There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
