Log Message:
-----------
set the TLON and TLAT arrays to an initial value of 0 before
doing anything else.  the subsequent code uses a where() clause 
before one set of columns in those arrays have been given a value.  
the previous code did not generate any wrong values, but testing 
uninitialized memory could cause FPEs depending on what happened 
to be at those memory locations.
