Or is that "only supports numerals"?

Sorry for causing all this noise on the Internet !!
Found the answer to this stupid question myself !
netCDF only supports characters. Thus it should be like this, and it is
rather s
urprising that ncdump produces strings for some files.
In IDL the solution is to read the attribute into a the variable and
then do a s
tring on it. Like this :
res=ncdf_attinq(fid, var_id, "title")
title=string(xx_tmp)
Perhaps it answers the question for somebody else !!
Best regards
