LeoNetCDF software application has some limitations
on the size of netcdf file that it can handle.
At first it is an instrumental limitation on the size of free RAM of the computer.
Secondly the tree control in MS MFC can handle no more then 64 K records.
To prevent undocumented behavior limitations (<10 K) on the number of displayed data in the tree control is artificially set. LeoNetCDF software application nevertheless can be used to work with large files including observing and editing their data in text XML file.
