Byoung-joo,

The compile time LLMXLN setting set set to 128 characters ($GEMPAK/include).
To solve your problem with long path lengths in file names, the easiest 
solution is to define
an environmental variable that represents the path, and use that in GDFILE, for 
example:

setenv DATAPATH=/long_path_name

then, GDFILE=$DATAPATH/filename

In GFUNC, if you have to compose long operations, you can use GDDIAG to compute 
parts of
equation separately.

Also, you can save a term that may be used more than once and refer to it by
an alias within a function using the '//' syntax (easiest to do in GDPLOT2
as a gdpfun expression).

The above solution can be done without recompiling GEMPAK with different LLMXLN 
settings.
