Re: [U2] FW: Clearing Input Buffer
Like David Green, I would have suggested CLEARINPUT. I'm missing something: why all these other schemes people are talking about?

What can I do to flush the input buffer at the end of my validation routine on my second field...or is it better to do this on the Process Before on my third field. It's more of a nuisance but it would look more professional if I could make it clean. Thanks.

Re: [U2] FW: Clearing Input Buffer
In BASIC you can loop/repeat on SYSTEM(14) or INPUT var,-1 If it's Unix, check your stty settings for ocrnl and onlcr. This may give you an immediate fix.

Re: [U2] FW: Clearing Input Buffer
You can also in the after routine of the second field, do a raw char input loop, until there are no further raw chars to input. -Original Message- From: David A.

Re: [U2] FW: Clearing Input Buffer
I would think flushing the input buffer in either location would be sufficient, assuming the problem is as you described. I've seen situations where there's something in the second field, for example, that is data stacking something new and the data stacking from the gun is conflicting with that. If you're confident that's not the case, flushing the input before that third field should suffice.

[U2] FW: Clearing Input Buffer
I have an input screen (built with System Builder) where data can either be entered manually or via a barcode scanner. The screen has 3 text boxes for input. The barcode option fills two of the text boxes and is supposed to land on the third box to await input. However, the scanner must be adding an extra return or something because when I scan it the third field's Process After executes. What can I do to flush the input buffer at the end of my validation routine on my second field...or is it better to do this on the Process Before on my third field. It's more of a nuisance but it would look more professional if I could make it clean. Thanks.
