Re: New Client Reply - [Support !MQN-848427]: Negative array size error

Carl,

i can't reproduce the problem. i have created an index for
2005-07-14-0900_us057g1010t04q060003000, read each data section, and
display each parameter without any problems. i also converted the file to
netcdf with Grib12Netcdf.java program that i've attached.

robb...
