In FORTRAN, windows and Lunix have different results.

I made a C-to-FORTRAN program a few days ago. I compiled it in windows and ran the result. I didn't expect the result to be wrong in Lunix. After searching for a long time, I thought it was the cause of the global variable. I didn't expect it to be the initial value problem in do while. Integer nNew I didn't set the initial value on wndows, but the operation is correct. I don't know what the initial value is in Lunix. At the same time, the running of do while in FORTRAN is not the same as that in C. If you get it done by yourself, I don't know the specific reason. I hope you won't make the same mistake.

 

Do While (nNew> 0) nNew = 0 do inew = 1, ncur, 1 xcn = nmatx (inew) ycn = nmaty (inew) zcn = nmatz (inew)
