So what is an ordinary programmer to do?
Years ago I guess I had nothing to do so I wrote a program that hooked into various LINK/LOAD SVC's and recorded the load module name (like Isogon and TADz do). That huge pile of data ended up on a tape and I wrote some code to scan the tape for a particular module, to find out who was using it and how often.
The scan took forever, so I worked quite a bit trying to make the main loop more efficient. Co-worker Stuart Holland looked at my logic and quickly switched it to using a hashing lookup algorithm, making it run probably a thousand times faster. Oops :)
