I bet that is inside a class CFORMAPPDoc?
you do not have the repeat the 'struct' in C++ just
DataRecord * FindARecord(int iRecordNumber);
will do.


 in the .cpp i declare this:

 struct DataRecord *CFORMAPPDoc::FindARecord(int iRecordNumber){


I suspect that you declared 'DataRecord' within the scope of class
CFORMAPPDoc
Thus change this to:

CFORMAPPDoc :: DataRecord  *CFORMAPPDoc::FindARecord(int iRecordNumber){

That might help.

Thanks Jan, That's the ticket. Too many subtle differences in 
declaration syntax for my two brain cells to get...repetition is the key 
to learning eh?
