Is it possible to execute a program within another program that requires parameters? (without inlining it)

E.g.

```
________________
 - PROGRAM:ADD
 - :Prompt A,B
 - :A+B>C
________________
 - PROGRAM:TEST
 - :For(I,0,20)
 - :Disp (prgmADD (I,I+1))
 - :End_________

```

Obviously this doesn't work the way it currently is, but I hope I made it clear what I'm getting at.
