RE: Hmmmm.....$1 Billion

[michael@xxxxxxxxxxxxxxxxxx]

Not being a C/S guy, I may be wrong, but my belief system is this:

A procedural program has the characteristic that the program tells the
user what they can do in the order the program wants; in an event
driven program, the user tell the program what to do in the order the
user wants. That's why people are talking about a loop in this thread
(no pun intended). A loop that waits for 'something' to happen and the
program keeps processing. Unlike a procedural program where the program
stops processing and waits for input from the user.

The RPG logic cycle is just a way of implementing a procedural program.
It will wait for user input and the program tells the user what to do.
The only advantage of the logic cycle is that it would automatically
(no additional code needed) read and write files and perform level
breaks. The disadvantage is the extreme lack of flexibility.
