Suggestion to use Fortran 90 syntax or newer where available

[monty241]

Code contains constructs like in ops_cals_stats.f90:
if (somcpri .gt. 0.0) then
Starting with Fortran 90 when I am correct (correct me if wrong), this can be replaced by:

if (somcpri = 0.0) then
which is easier to understand by coders recently graduating. Replacing some other traditional Fortran constructs by more modern constructs might also help adoption.

recently graduating

I think this is needlessly derogatory...

• Not every coder actually has formal education in coding
• Not every coder that has trouble with "if (somcpri .gt. 0.0) then" is new to code in general, some are just not native in fortran.

First of all, we'd like to apologise for the late reaction. We'll try to reply more quickly to future issues.
Thank you for your suggestion. We are continuously working on improving the code quality and readability of the OPS model. We will update this issue if this is implemented in a future version.
