Unfortunately, it didn't run so fine when plugged into the actual production box. Turns out the timing diagram on the USART chip didn't match the actual timing of when the chip presented an interrupt. The early interrupt caused a jump to an "unpredicted" location. The ICE slowed everything down enough that the interrupt didn't occur before we were ready for it <grin>.

Early Quantum Computing, eh? You can't debug the code without effecting it. <grin/>

It really was a trip. But it did make me realize that, in the end, there is no magic. It's 1's and 0's, and the computer does exactly what you tell it. The problem comes that as software becomes more complex, you abdicate more control (whether it's to a chip, a program, a language, or a framework) and the less you understand, the more it seems like magic.

Which is why I understand your general dislike of 4GLs like EGL. It requires a level of trust, and I've never trusted anything quite as much as I trust the combination of CPF and RPG, whatever the current incarnation. And that in turn is why I still count on RPG for my business logic.
