Parent GUI generates N copies of child GUI

I have a program that takes number of breakpoints(N) and for each breakpoint request the type of signal to be drawn for the current segment

Example

The signal is defined from -1 to 0 as a DC signal and from 0 to 1 as

ramp and from 1 to 2 as cosine the user will enter that the number of break

points =2 and the positions at t=0 and t=1

My question

I want the parent GUI (signals.fig) to generate (N+1 : number of segments) copies of (DrawInfo.fig) where each(DRAWINFO.fig) requests the user input for the current segment ( in the above example 3 segments : -1 -> 0 -> 1 -> 2) then it closes and opens another(DrawInfo.fig) for the next segment and so on.

How can I do that?

With a loop? This sounds trivial, so I assume that I do not understand, what you are asking for.
