Hello all, From Steve Chiswell, former developer here at Unidata: "When text is backwards and flipped 4321 or 21 43 as below, the problem is the MCHPRM defines the wrong machine type byteorder. Eg, they have created something that doesn't match, or used a compile flag (such a gnu has) than defines byteorder which doesn't match the expected routine #ifdef's. Also, if files are being created huge, then you probably need to define unspecified reals and integers as 4 bytes. The compiler may be defining them as I*8 or I*16 by default for the system. Steve" 1) MTMACH is what to check in the files in $GEMPAK/include/gemprm.h against the compiler options used in $NAWIPS/config/Makeinc.* files 2) try forcing with flags -i4 and -r8 -Michael > Thanks Reuben, > > I don't see anything obvious in the log that tells me what is going wrong.
