Re: Called routines sending values back to the calling program

hi Roy,

There isn't really any setup or tricks to it. When you change the value of a parameter, it'll automatically be changed in the calling program.

So all you have to do is have the caller pass a variable for the "returned number" parameter, and then set that parameter to the value you want to return.

It's really that simple.

does a programmer structure the called program to pass a parameter back to
the calling program? And what has to be done within the calling program to
receive the parameter being passed by the called program?
