I am looking for a way to validate email domains from COBOL in a interactive data entry environment. In my application users will enter email addresses provided by our customers. The domain of the email address provided is not always valid. I am running Server Express on top of HPUX 11.32. I am familiar with the nslookup command and have written a test program to execute this command calling the SYSTEM subroutine. I can't seem to get the command to pass back to COBOL a return code and anything for that matter to designate whether the command was successful or not. Anyone have any ideas how to validate email domain names from COBOL? Thanks in advance.
