I’m a FileMaker geek, and I was creating a solution on spec for a client. One set of files was going to link up with the others but to create it I needed an export file from their AS-400 which they had not supplied me yet, to get the file and field structure for that portion of the data. So in the mean time, I created a single stand-in file, “dummy”, and referenced it in places where I’d be referencing the real file once it was created.
Eons later, long after I’d finished the project and billed them and turned over the final product for them to use, I get an irate phone call because there’s a message on screen calling the operator a dummy. (“Unable to find the file ‘dummy’. Please locate file and click ‘OK’ to continue.”). (User had somehow triggered a defunct subscript that wasn’t supposed to be called by anything, and which had a long-forgotten reference to the stand-in file. Of course.)
