The UIO module allows the reading and writing of files
in little_endian
and big_endian format.
In 3.6 the preprocessor switches are listed, that control the
modern - single - version uio_mac_module.F90 of this file.
-assume byterecl: Necessary for the UIO routines:
specify that the length of a record is measured in bytes (and not in words).
-cpp: invoke the preprocessor on all source files.
-inline speed -V: Force automatic inlining,
optimized for speed.
-O4: General optimization.
-Drhd_hyd_roe1d_l01=0: Optimization: Choose standard set of routines for
Roe solver.
See Sect. 5.4.17.
-DMSrad_raytas=0: Optimization: choose default version
of loop in SUBROUTINE raytas in file MSrad3D.F90.
See Sect. 3.6.
