OK, I'll bite. What is/was the intended purpose of controlled storage? I remember when I first was learning PL/1 (too many moons ago to count) being fascinated by it, but at that time I couldn't really see what the advantage(s) of controlled storage over based storage were. Than I had to move on to a non-PL/1 shop and I kind of lost track of it. TIA for curing my ignorance.
