Re: Buffer overflow error

Yes, the variables are defined. Further, the $inputFile actually exists
(checked by putting an ls $inputFile before the surface command).

Here are some more clues. I'm trying again to run the command manually.
When I use the -Lld and -Lud options, I get the buffer overflow error. When
I omit these options, the surface command executes properly and writes a
grid file.
