Pathpilot Subroutine - Prompt user for input?

Is it possible to have a subroutine ask for user input?

I would like to create a looping subroutine for boring hole that ends when the hole is on size.

The subroutine would work something like this.

>Call sub from main program

>>Prompt user to enter the starting / rough diameter of the hole. [ ]

>>while statement (while current diameter < finish diameter)

>>>Gcode to bore hole, and move head out of position when done

>>>Prompt user to measure hole and enter new size [ ]

>>End While
>End Sub

That wouldn't be ideal for what I am looking for. I would like to do it with a subroutine so that the block is milled 100% complete with one NC program. I had a similar routine that was for Fadal Controls that I used. In my experience it reduced the likelihood of error compared to a Conversational setup.

That would of course depend upon whether or not the subroutines support user input.

Yes I believe that it is possible. Andy had helped me set up something like that once. I can't remember all of the details, but I think it may have involved G-code remapping. It was all documented on the forum here, I'll try to dig up a link.

Here is a link to the thread. I believe it should be just what you're looking for.

Thats exactly what I am looking for,
Thanks.
