source: CONFIG/UNIFORM/v5/LMDZOR_v5/GENERAL/PARAM/orchidee.def @ 1893

Last change on this file since 1893 was 1893, checked in by jgipsl, 10 years ago

Corrected bug in lmdz.driver introduced by myself in rev 1892 :
Before used IGCM_sys_Put_Out to copy Bands file into PARAM in submitdir but this is not possible at IDRIS. Changed to use IGCM_sys_Cp instead. Sorry.
