Hi, I wonder if anyone could help. I have a file that is made up of an array of structures (all of identical type). Each structure is a record containing many fields of differing types, int, float, char array, etc. I want to load the whole file into memory so that I can get quick access to individual records. I used to do this in the old C++ 16 bit programs and found that if a record straddled a 64k boundary, it would wrap back to the beginning of the sector. The pointer could be set at the beginning of the record, and if MyStruct->field7 was on the other side of the 64k boundary, it rubbish. So I had to copy the record byte by byte to get an intact record. The question is: does the same problem exist with CBuilder which is a 32bit program? Cheers, David
