The macro commands emaildata and vnmremail have been modified to use a default email address defined by a VnmrJ parameter email. If you have an indiana.edu email account and prefer to email files to there, you don’t need to change anything (i.e. leave email=”). If you don’t have an indiana.edu account, you would need to set up the email parameter to provide a default email address, e.g. type email=’email@example.com’ in the VnmrJ command line (presuming your IU user ID is abc).
See this previous post for more details about emaildata and vnmremail.
Please also note that a bug in the emaildata and vnmremail macros on I600 which prevented using the default email address has been fixed.
