  1. Things and Thoughts on TM5 looks • Modules only (no subroutines, functions ‘hanging’); File-name = module-name.f90 • Declarations: explicit or by ‘use, only’ (statement use without only prohibited) • Output arrays of modules are declared globally in the module (or the exception is indicated) • Initialisation/reading routines are brought together with the processing routines in one module • Module flow diagram based on module functionality to guide programming • Settings (paths, names, project, namelist) brought together in one rc-file, incl. switches between compilers, platforms, libraries, (MPI, HDF/netCDF, …) • Uniform code formatting (e-macs(?) convention on indents, max line length, etc.) • PRISM CF conventions (naming variables for I/O, physical constants, metadata, …)
