# Array Transfer

Subroutines with data arrays transferred to or obtained from GREG have a Real*4 and a Real*8 version. The simple precision has a name beginning by `GR4_`, the double precision a name beginning by `GR8_`. In the argument list description, `REAL` will mean Real(KIND=4) for the `GR4_` version, Real(KIND=8) for the `GR8_`. These routine work by copying the data. For really big arrays, it is more efficient to transfer the information by reference, though SIC variables (see the SIC manual).
