The problem is when you interrupt a program currently running a subroutine at a deep level. If you launch a second program, when those return adresses from the first program will be cleared ?... If not, they would prevent the return stack to use of all of ts 7 levels in the second program ...

Right!

In fact, you can also launch the second program with 'f E' or with 'GSB E', for example!

Keep yourself healthy!
