I'm not sure what you mean - there was no encryption in this app. Data entry applied barcodes to film canisters. The film sorting robot read the barcode and passed it (through &DEVICE& - what fun) to a routine that looked up order characteristics (e.g. 2 sets of 4x6 prints, slides, CD, express shipping) and calculated a bin number and returned the bin value to the robot. If the robot didn't hear back in less than .05 seconds, it defaulted to an error bin. The robot then dropped the roll into the target bin (actually it spun a J-shaped tube on a carousel the size of a Volkswagen and blasted the film down the tailpipe with a burst of compressed air).
Testing this was similar to your issue of typing in long barcodes. I needed to "type" in thousands of barcodes and validate the results against (table driven) business logic changes - i.e. sort "express" and "retail" together. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mark Johnson Sent: Sunday, November 20, 2005 8:29 PM To: [email protected] Subject: Re: [U2] 20 Digit Number So what was the secret and was it human-able.
