You can send emails in InterForm400 with email commands as an alternative to an email finish definition.
The two major email commands in InterForm400 are:
1.The merge spooled file to PDF, MRGSPLFPDF command.
2.The send email, SNDEML command.
InterForm400 also contains other, older email commands (for backwards compatibility), that offers a subset of the functionality in the SNDEML command.
