First, the NGRB2PCGRD32.EXE in the current version of PCGRIDDS32 is different from the version in WINGRIDS, maybe you can include the latest in the PCGRIDDS executables. The WINGRIDS version convert grib2 but the PCGRIDDS32 version doesn't (I may just have an older version but can't get the executable without downloading the complete version).
Second, the thing I found in WINGRIDS are in the /USER/ files. Some of the ftp routines have incorrect addresses and some have incorrect formats. I have only found a few so far and I'll try to let you know when I find others. A few of note:
In NMB2002.DAT, the address is
and should be
but there is also a problem with the position of
which should occur later in the string. This is also true for NMB2062, NMB2122 and NMB2182.DAT/DF.grd1/
I will try to document all of the errors and fixes and post them when I find most of them.
