gfortran&ifort

梦纯

When using gfortan to write a file, please set the format to "unformatted" and access to "stream" , because gfortran  cannot use "binary"  , and this is a formal format to write a biary data.
for example:   open(18,file="his_CDD.dat",form="unformatted",access="stream",status="replace")

In ifort, you can still use open(18,file="his_CDD.dat",form="binary",,status="replace") , but the abovementioned example is strongly recommended.
