I wrote my first program on a yellow pad just over 61 years ago. If I remember correctly it was called Fortran 4. A key punch operator took the sheets and returned shortly with a deck of cards with holes punched in them. She called the deck a source deck. I fed them into a card reader connected to an IBM mainframe. It responded by punching me a new deck called an object deck. I combined this deck with a bunch of other decks called library decks and fed them into the same card reader. This time I received a deck called an executable deck. Using my yellow pad again I listed all the input data and received another deck called input deck. Placing this on the front of my executable deck I once again approached the card reader. After entering this deck, I received a printout of rows and columns of digits representing the flight performance of the engine and airplane our company was developing for the military,
A couple of years ago, I decided to try my hand at programming again. I purchased a couple of books on C++ and downloaded some stuff called Allegro.
With the list of reserved words (as they were called) and the description of what they did and the examples, I was able to get a program up and running that filled the screen with random colored pixels and then set back and watch as it did a bubble sort, bubbling the lighter colors to the left upper corner and the darker to the lower right corner. My great grandchildren loved watching this program, But my computer died of old age so I replaced it. The new one had an Intel processor and a new OS so my bubble program would no longer function.
Then I saw on the internet Simple and Fast Multimedia Library. The kids liked the Hanoi's Tower game so I decided to give it a shot.
I read the tutorials, the documentation, and the forum pages but could not find any indication of reserved words or their function. So after many weeks of frustrated try and fail I finally arrived at the enclosed. Not good but is appears to work.
