Documentation Question

[Jeremy.Martin at noaa.gov]

Thanks,

I looked at it again and I found that section. I guess I am just a 
little confused on the exact use of some of the functions. I am very 
new to the whole GEMPAK world and I guess I am still a little confused 
on the format of some of its programs. For instance I understand 
that // is used to store one function basically as a variable and ! 
seems to separate the individual functions. However I was looking 
through the list of functions and I get really confused on the Boolean 
and less than greater than functions. For example say you had some 
grid where everything above a certain threshold needed one value and 
everywhere else needed another. Do you happen to know any place that 
has good examples of using these functions?

Thanks again for your help,
