But WHY do you want to do this ? Why dont you call the child programm directly ?
I am confused about your motives. It looks to me you are just putting a hypothetical case here. I don't see why you want to submit another program like this.
There must be a reason why you want to do it like this. There is NO WAY that you can get the internal table values of a program you call like this without changing the child program. Unless you want to see the result of your child program, but then you can call the child program directly or use the exporting list to memory statement
You need to tell us WHY otherwise it is impossible to help you.
