Close but not exactly. It's a prg with many functions in it. If it's just a prg you wouldn't need to "set proc to .." but directly call it.

* Myfunc.prg
lparameters tuPar1
return type("tuPar1")

You call above function directly - ? myfunc("hello").

* myprocs.prg
function fun1
return 1

function fun2
return 2

*....

This is a procedure file, a prg, keeping many functions. Calling :

set procedure to myprocs additive
? fun2()
? fun1()
? anotherfunction()
