There're two classes in the download section that allow to work with structures
and pointers in VFP: file #986 and file #9557. You'll have to figure out if you can use one of them for your task.

>Can this structure be emulated in VFP 6.0? I have tried declaring an array of 70 elements, I also tried one long character string... until I realised that CHAR* was apointer to the value rather than the value itself. Any ideas?
