limit_read_mod.F90 @ 4766

Last change on this file since 4766 was 4619, checked in by yann meurdesoif, 16 months ago

Suppress usage of preprocessing key CPP_XIOS.
Wrapper file is used to suppress XIOS symbol when xios is not linked and not used (-io ioipsl)
The CPP_XIOS key is replaced in model by "using_xios" boolean variable to switch between IOIPSL or XIOS output.
