Last change on this file since 11624 was 11624, checked in by acc, 5 years ago

Branch 2019/dev_r11613_ENHANCE-04_namelists_as_internalfiles. Substantive changes required to replace all namelists with internal files. These are the key changes only; to compile and run tests all REWIND and CLOSE operations on the (no longer) units have to be removed. These changes affect many more files but can be scripted so are not included here in order to make a later merge easier. The scripts used to prepare code for testing are included on: wiki:2019WP/ENHANCE-04_AndrewC-reporting/Internal_Namelists. With these additional changes this code passes most SETTE tests but the AGRIF preprocessor does not currently accept the new allocatable character strings. To be investigated.
