A Computer Program has four kinds of logical parts.

The “Ions.”

• Function:
  • An operation
  • A procedure
  • An discrite algorithm
  • Where a change is made that is not just a logical change
• Information:
  • States are recorded
  • Variables
  • Files
  • Packets
  • The smallest measure in all possible worlds is the bit.
    • The difference between this and that.
    • Yes and No.
• Repetition:
  • When something is repeated.
  • When something is repeated.
  • In essence it is a type of conditional.
    • If a condition is true do these conditions until the condition is false.
• Condition:
  • This is where the program makes a choice.
  • If this then that.
  • If not this then not that.
  • Conditionals drive the magic of computing.
  • They are logical combustions.

Any program can be broken down into these parts. I cannot conceive of  a program that cannot be broken down to these parts. My analog wrist watch is a computer program with these logical parts.

1. Function: The date dial turns.
2. Information: The numbers involved.
3. Repetition: The tick and the tock.
4. Condition: If the hour hand hits twelve advance the day dial.
   1. Etc…

If you are trying to understand a computer game then consider that the first method is to break it down into the hierarchy of its parts.
