Make sure you remove all library file in $GEMLIB before rebuilding to ensure that the value gets propagated everywhere. In the 5.4 distribution, the max number of grids in a file was 10,000 and dcgrib can use -m 10000 to create the file with that size. I've upped that size for the next release, and see that the combined NMC2/HDS 212 grid file I have for 12Z today contains 11,845 grids. I've defined MMHDRS=30,000 currently for the next distribution thinking about ACARS, NLDN, shef and other growing observations. If you have any thoughts on that size, let me know. Steve Chiswell
