Rev's "Cards and stack" metaphor can be traced though a long history of stack-based programming. For those of us not entirely familiar with its idiosyncrasies, in can be a bit "unfamiliar."

For instance, I have a stack of cards, some to be kept, some discarded. In the processing of my program, I decided to try to "work within the metaphor."

I started by marking all the cards (??).
I then worked with my data a bit, all the while "unmarking cards" to be kept. My thinking was that the system would allow me to "delete marked cards" at the end of the cycle. I stupidly thought that "delete marked cards" would work.


Which, of course, I haven't seemed to be able to make it do. I feel elementary when I have to ask, how does one delete all the marked cards in a stack? Frustrations like this will send OOP experienced programmers running from this environment.

The syntax and metaphor may seem "easy" to some, but to me it creates MANY more hurdles than the logic flow of my program, which is pretty sophisticated. I get errors like "bad grammar" and "sloppy handwriting" and "late for class" thrown at me all the time. I feel like a child that didn't bring in his homework when this stuff comes up.

But, I endeavor to persevere. Is there a better technique than what I've described? Failing that, how does one delete all the marked cards in a stack?
