[ncl-talk] Convective Temp Calculation

Dennis, thanks.

I added that.. Added the NCLFORTSTART/NCLEND to it, etc.. Then, I just
continued to get a ton of other functions that were undefined... So, I went
through and added them all one by one until finally I got no more errors..
I basically have the whole sstats.f file in there..

Now, I get this error - warning:Could not find Init() in external file
/home/Soundings/Extra/test.so, file not loaded
warning:error at line 17 in file testsounding.ncl

I do get a syntax error when running WRAPIT now, too.

I sincerely appreciate your continued help... New test.f attached.
