Re: fatal:syntax error: line -1 before or near .

Mary,

Attached are simple test cases for C shell (csh) and Bourne shell
(sh). These demonstrate the problem for me with the following NCL
versions and platforms. The problem also occurred in previous NCL
versions:

    NCL 5.2.1 Mac OS 10.5.8
    NCL 5.2.1 Mac OS 10.6.4
    NCL 5.2.1 GNU/Linux (X86_64)

To run the demos:

   ./exit-test.csh < list1
   ./exit-test.sh < list1

These should run cleanly as is. To trigger the exit problem,
comment out the "exit" statement at the end of exit-test.ncl. I get
messages similar to Justin's:

   fatal:syntax error: line -1 before or near .
   etc.
