Just a comment: The config file for nsharp has a default section for the retrieval of data ($NAWIPS/resource/Nsharp), which states: ! ######################################################################### ! Data locations if environmental variables not found, default will search: ! $GEMDATA/upperair, $GEMDATA/acars, $HDS, respectively ! Even if $GEMDATA and $HDS are defined before compile time, they are not used at runtime. Instead the values defined in $NAWIPS/resource/Nsharp are used: Nsharp*obssndg_sel.pattern: /data/ldm/gempak/upperair/*upa* Nsharp*acarsndg_sel.pattern: /data/ldm/gempak/acars/*acars* Nsharp*pfcsndg_sel.pattern: /data/ldm/gempak/upperair/*.snd Nsharp*mdlsharp_sel.pattern: /data/ldm/gempak/hds/*.gem Nsharp*sharp_sel.pattern: /data/ldm/gempak/* Shouldn't $GEMDATA and $HDS be the default?
