Thanks guys. I DO have that AKB, but I've tried it in the past, and couldn't get it to work properly. I think the way it was explained by Adamn, I now realize what I was doing wrong.
So the commands, BEGIN, SETTLE, etc, all go into the REQ file, right? Then winhook calls a batch file, and within that batch file are instructions to copy the REQ file into the EDC directory, and EDC takes care of the rest? Is that all correct?
One of the techs I used to work with DID have a neat little batch file (I think I still have it) that did this, and it would also tell you if it did not settle properly. However, I agree with the comments from Bo and Synic. For one thing, your talking about playing around with the customers money here, and if something goes awry, they get angry real fast. Also, what exactly are we saving them here? Batching credit cards takes like a whole 3 clicks of the mouse. Big deal.
To add to your comments, the most annoying this is that when it did not work automatically, the customers acted like the system was "broken". Then I'd tell them, "Look, this is an enhancement to the system that we don't really support. If it doesn't work, you've just got to batch it manually."
And of course, like many customers who get used to doing things the "easy" way, they whined and cried like babies that they now had to do the batch themselves. I finally got so fed up with it, that I went to my boss and said "We've got to stop offering this to customers. It's risky, and it's not something we should support." My boss agreed.
So, to end this story, this is for one of those customers who is insisting it be returned, and acting like a baby about it. We just replaced his file server, and because the old hard drive failed, I had no idea his batches were being done automatically. And.. you guessed it.. he's making a big old deal of out of it. He keeps his office locked, and because he gets their after the restaurant opens, and leaves before they close (must be nice!), he either doesn't trust anyone or does not want to appoint anybody to peform this "oh-so difficult task" of batching manually (note my sarcasm here

).
So, I pretty much have to set it up for him.
