HI All , Have downloaded the latest snapshot - netcdf-4.0-snapshot2008022202Its 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 HenryIn 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. */
