Sub-routine returning multiple values
I haven't found any mention of it, but thought that it might be something already implemented?

What I'm curious about is having a sub-routine calculating multiple values and returning those values back to the function that called it. Currently what I'm doing is returning a list of values form the sub-routine, then one by one assigning to the variables I want. A completely made-up example illustrating what I'm talking about:

Code:
...
  my_vars:=Sub_Routine(a,b,c);
  d:=my_vars(1);
  e:=my_vars(2);
  f:=my_vars(3);
...

Sub_Routine(x,y,z)
BEGIN
  RETURN({x+1,y+2,z+3});
END;

It would be handy to be able to reduce the four lines to a single line, some like (d,e,f):=Sub_Routine(a,b,c); or something like that. I haven't fully thought this through yet, but couldn't help thinking there could be a better way.

Any insights or further thought?
