Some days ago I've heard from someone telling me that back in his days they were using an upfunc function/keyword (don't know what it is). I didn't ask him what it was and what it did, but I can't get this upfunc out of my head. Must be 20-25 years back, when he was programming.
So I'm asking the programmers here:
Is there any (older) programming language featuring an 'upfunc' function or keyword?
The single context I can provide is that it was mentioned in a yes/no selection scenario.
