GDDIAG problem in GEMPAK

[Melick, Christopher James (UMC-Student)]

Hello,
 
I am having problems with the output generated within GDDIAG when I am declaring a parameter in GRDNAM that is the quotient of two parameters, the one in the denominator encompassing a large range in scales [in this instance, the squared difference of the vertical change in geostrophic wind].  Several grid points will have identical values if I use the newly generated grid file which should not occur.  However, a completely different and more accurate result will occur if I manually type in the quotient of the two parameters myself in GFUNC.  What causes this and is there a means to fix it??  I hope I have explained my dilemma clearly and completely enough to follow.  There are no GEMPAK errors in the logfiles and I have tried creating a separate script just for this particular term with no success.  
 
Thank you very much,
Chris Melick
