Well, All I know is that PBP is beyond me in some important areas. I did download Flowcode 5 and I really like it. Sure there will be some learning to do, but within 30 minutes I created my first program. A stepper controller. Just about everything that pisses me off in PBP, including dts, tmro etc., all have drop down menus and such. Just what I was looking for. So I'm afraid that PBP has lost me as customer. There is just to many vague concepts that are just beyond my capacity to understand, as a matter of fact, after spending $250 for PBP i'm more than a little pissed off.
