Proposition to declare a variable for character size

[olegallou]

In Nemo, we declare the character with :
example :
sbcrnf.F90: CHARACTER(len=32) :: cl_rnfile

and for any use, we want have more than 32 character.

We propose to declare in par_kind.F90 the variable :

INTEGER, PUBLIC, PARAMETER

& !: Character section jp_lenmax = 256 !: Lenght of Character strings

and use this variable for all the character declaration.

That's a very good idea !

In par_kind.F90, we add a variable "lc" :

INTEGER, PUBLIC, PARAMETER ::   lc = 256   !: Lenght of Character strings

and modify the module_example:

CHARACTER(lc) ::   clname   ! clname description (default length, lc, is 256, see par_kind.F90)

We start to introduce CHARACTER(lc) in  3 modules (nemogcm.F90, IOM/in_out_manager.F90, oce.F90). This has to be generalised to all the modules.
