Meaning of "." between terms in Fortran

Meaning of "." between terms in Fortran

I am trying to understand some Fortran code that contains the following:
IF(NT.NE.0) GO TO 15
Could someone please explain this "." operator is / does?
Thank you.

RE: Meaning of "." between terms in Fortran

In oldish fortran (post Fortran II, 1966 std), the comparison operators are .ne. .eq. .le. .ge. .lt. and .gt.

The logical operators are .not. .or. .and.

Your statement reads if nt is not equal to zero goto label 15

That's really helpful, thank you!
