Dear all,

It’s a bit long to explain why, but I need to output  
a variable in quadruple precision in NEMO using XIOS. However, the compiler refuses to compile if I try with such an error message:  
/cluster/home/robinson/nemo4/r4.0.4/cfgs/SPITZ12/BLD/ppsrc/nemo/trdtra.f90(580): error #6285: There is no matching specific subroutine for this generic subroutine call. [IOM\_PUT]

Is there an easy solution to this ?

Thanks for your help,

Robinson

Hello Robinson.  
Do you mean real(16) in Fortran?
