[gradsusr] if else statement with string arguments

[Jeff Duda]

Have you verified that no additional characters or spaces are being input
to the script? Try

say "_"region"_" to check that there are no extra spaces in region. Also,
in your if statement, there does not appear to be a space in ='conus'.
While I doubt that is the cause of the problem, insert a space there to
check formatting.
