I've not had an answer to this to my satisfaction about automatically extendable user spaces.

For example, let's say you have created an automatically extendable user space US1 of 700 bytes, and we assign the pointer to this user space to pointer variable p_US1.

Let's say I initialize another pointer p_Pointer2 to be ( p_US1 + 701 ).


Assume also there is a character variable CHAR10 of length 10, and the pointer for the variable has name p_CHAR10.

Next we assign a value of ( p_US1 + 700 ) to p_CHAR10.

What happens if I  assign a value of '1234567890' to CHAR10?

*In other words,* I cannot presume the extendable attribute to mean you can put a value into anywhere at any address in storage and expect it to extend  the  user space.

Or, exactly what happens under the covers to accomplish appending storage to the user space?
