HI All ,
Have downloaded the latest snapshot - netcdf-4.0-snapshot2008022202
Its seems that the configure flag "--disable-oldident" enables
regular necdf3 names and when it is not present the new classic name
mode enabled . --enable-oldident seems to have no effect.
see below comments from the source code
Regards Henry
In netcdf3.6.2
/*
* Verify that a name string is valid
* CDL syntax, eg, all the characters are
* alphanumeric, '-', '_', '+', or '.'.
* Also permit ':', '@', '(', or ')' in names for chemists currently making
* use of these characters, but don't document until ncgen and ncdump can
* also handle these characters in names.
*/
In netcdf4 running in classic mode
/
* Verify that a name string is valid
* CDL syntax.
* The allowed syntax (in RE form) is: [a-zA-Z_][a-zA-Z_-.+@:()]*
* The characters after '@' are allowed to support names for chemists.
* This definition must be consistent with the one in ncgen.l.
* If UTF8 is supported, then a multi-byte UTF8 character can occur
* anywhere within an identifier.
