+!--       Read the parameter file. Therefore, inquire whether the file exist or 
+!--       not. This is required for the ocean-atmoshere coupling. For an ocean
+!--       precursor run palmrun provides a PARIN_O file instead of a PARIN 
+!--       file. Actually this should be considered in coupling_char, however,
+!--       in pmc_init the parameter file is already opened to read the 
+!--       nesting parameters and decide whether it is a nested run or not, 
+!--       but coupling_char is still not set at that moment (must be set after
+!-        the nesting setup is read).
+!--       This, however, leads to the situation that for ocean
+!--       precursor runs PARIN is not available and the run crashes. Thus, 
+!--       if the file is not there, PARIN_O will be read. An ocean precursor 
+!--       run will be the only situation where this can happen.
