Re: Need help with referencing fields within a construct

As long as you don't mess with OPTIONS FIELD ORDER UNCONSTRAINED, your analysis should be correct. Oh, and there are other conditions too, such as there is a field after the last field to be skipped, and a field before hand, and there's more than one field to skip. Lose any of those and life becomes a whole heap harder. Been there; done that; codified the results; have forgotten the details but know where to go to find them. If you ever get really brave, you can write code to do seamless wrapping across three forms, so that when you go up from the first field on the third form you end up in the last field on the second. That's really rather tricky! Info Temp wrote: > June Tong wrote: > > > Can't find an 'Oops', but yes, I believe you can do this.
