Michaael,

the mod_savefile is in the not yet officially released version 4.1 of RegCM.

We have introduced those two subroutines to gather all savefile related 
activities in a single dedicated module. In the 4.0 code the two subroutines 
init and spinit read the savevile in different parts, and the output subroutine 
writes the savefile, for a total of three files with I/O operations. Now all 
read and write operations are gathered in the mod_savefile, and those two 
subroutines appear called by mod_init and mod_split. They are called "part1" and 
"part2" because the data in part2 (split explicit data and boundary conditions) 
are read from file after those in part1 (status variables). mod_savefile now 
contains all reads/writes to the unformatted SAV file. As this file is used only 
for internal purposes and is not a model output, the I/O format has not been 
migrated to the 4.1 common NetCDF.
This gathering allows easier and hopefully consistent modifications to the 
savefile format to be performed editing just the mod_savefile module.

Ciao!

Graziano.
