[parallel-netcdf] #30: Action prohibited on NC_GLOBAL varid

[Federico Carotenuto]

Dear Wei-keng,

Thank you for your quick reply! Sorry if I'm replying via email but I can't
find an option to reply to the ticket directly.

I followed your suggestion and modified the source code in the following
way, in order to echo the value of emisa_times_varid before NCERR

write(*,*) "EMISA_TIMES_VARID =",emisa_times_varid
ncstat = nfmpi_get_vara_text_all(emisa_nc%id, emisa_times_varid, &
         &   (/i2offset(1), i2offset(ihourrun+1)/), (/i2offset(dlen),
i2offset(1)/), datebuf)
write(*,*) "EMISA_TIMES_VARID AFTER =",emisa_times_varid
          NCERR(__LINE__)


In both cases, before and after the call to nfmpi, the value of
emisa_times_varid is 0.

As your links states that is effectively the NC_GLOBAL constant for
Fortran.
