OK, I downloaded the file and see the problem.  When you generated
DataModified.cdl on a Windows computer, it has changed the endings of
each line by replacing the single new-line character of the CDL file
with a carriage-return and new-line character.  ncgen gets a syntax
error on the first carriage-return character it sees and exits.  You can
see that DataModified.cdl has these extra characters by looking at the
size of the new file compared to the OriginalData.cdl.  The new file is
109351916 bytes, but the original file was about 107723284, without all
those extra \r characters used as line endings on Windows text files.

This is a problem that I have not seen before with ncgen, because it is
used on CDL files that come from ncdump, which do not have the extra \r
carriage-return characters before each newline.  I will eventually fix
this in ncgen, but in the meantime for your problem, I just used a
program named "dos2unix" to change the line endings to match what ncgen
expects, just a newline character.

Then ncgen works fine, until it encounters the last line of temp values,
which ends with a "," rather than a ";", and it gets another syntax
error:

    ncgen: DataModified.cdl line 795855: syntax error

  // temp(23,11,54, 0-54)
    264.0619, 264.099, 264.1099, 264.0779, 264.0126, 263.9439, 263.9188,
    263.9339, 263.9385, 263.9156, 263.8802, 263.8372, 263.8124, 263.8065,
    263.799, 263.7932, 263.7779, 263.7554, 263.7683, 263.8624, 264.0413,
    264.2074, 264.2559, 264.1556, 263.9081, 263.6698, 263.6201, 263.6891,
    263.7142, 263.6941, 263.6813, 263.6721, 263.6609, 263.6432, 263.6154,
    263.5957, 263.6472, 263.815, 264.0381, 264.1737, 264.0785, 263.8011,
    263.6033, 263.5968, 263.6905, 263.9261, 264.1966, 264.1403, 263.8568,
    263.6507, 263.569, 263.6014, 263.6422, 263.65,  263.645,

I fixed that in an editor, replacing the last line with

    263.6507, 263.569, 263.6014, 263.6422, 263.65,  263.645;

Then ncgen worked fine on the resulting file, creating the corresponding
DataModified.nc netCDF file.  I tried to upload this to your
www.adrive.com account, but it got an error after a few minutes of
uploading:

  Connection Interrupted
  The connection to the server was reset while the page was loading.
  The network link was interrupted while negotiating a connection. Please try
  again.

Instead of trying again, I put the file here, so you can download it:

  http://www.unidata.ucar.edu/staff/russ/public/DataModified.nc

which has size 36023772 bytes.

Please let me know if you can't access it.

Later, I will send a small Fortran program that adds 4 to each of the
values of the temp variable as well, just to show how to do it in
Fortran.
