What is in $b? Where is $CMB? Why do you expect the value stored in a hash to change once it's been set? Why are you not rolling the die each time the user inputs a request?

If the computer were a person, here is what that person is doing currently:

  1. Roll a die, and write down the result.
  2. Roll another, and write down the result.
  3. Roll again and write down the result.
  4. Read the first result and write it again into a little book of indexes and corresponding values.
  5. Read the second result and write it again into a little book of indexes and corresponding values.
  6. Read the third result and write it again into a little book of indexes and corresponding values.
  7. Repeatedly ask someone what they would like to know.
  8. Look in your little index book and find the answer that was written down for the question that was asked.
  9. Read back to the user the answer that you wrote in your little book.
  10. Wonder why the answer written in the little book hasn't been magically erased and re-written without your intervention.

In real life, as a person, you would roll the dice each time someone requests a roll. In your program, you roll just one time and store the result. I don't think that caching a die roll is the right approach.

    [ambrus]: (Also a lot of manual intervention by two or three other co-workers, who do other parts of the process.)
    [ambrus]: Some of the manual part is unavoidable, but not all.
    [choroba]: LanX was there a way to recover the numbers from the remaining information?
    [Corion]: LanX: Ow ;)
    Discipulus manual work: i just tell the same to my boss: every time the quick solution is to assign some manual data entry task to my group.. because we have not direct access to many databases here..
    [LanX]: point is: in high speed trade each bank has to remember what he has to get from the others... so dresdner got billed for losses but couldn't claim gains
    Discipulus is this the IT?
    [Corion]: Discipulus: Well, in many cases it doesn't make sense to build an interface and complicated program just to enter 20 rows into a database ;) But yes, automating data imports should pay off in the long run
    [LanX]: Choroba: this happened before I joined, was still in uni, but my boss was summoned to the CEO of the second biggest German bank at that time and could only say " I told them its not ready" ;)
