Quit when an error occurs

[Diane Stokes]

Davide and Marcus,

The following works for me in 1.8SL11 and 1.9b4 on AIX.

If you include the "x" option, eg:
    grads -blcx myscript.gs
grads will quit when the script/command is done, even if it terminated
early due to error.  An error code is returned to the operating system
if you want to check that the script ran successfully.

Is that what you were looking for?
    Diane
