Digestify command

Ladies/Gentlemen
There is a command under MSG on ULTRIX v1.2 called "Undigestify".  
Undigestify works nicely to undigest such things as the unix-wizards digest.

Problem: I can find no corresponding command "Digestify".  Obviously, I can
horse around and get a bunch of messages into a file and delete the lines with
"ctrl a" and insert a string of thirty hyphens between messages, but that 
seems less than elegant.

What am I missing ?
