Helene,
the compilation fails because you try StrCopy to a const char*. This is
not allowed. At the other hand you haven't allocated the space for your
string. So if the compiler hasn't complain you would have run into a big
memory trash. So you either use the way as the structure is initialized
in the example or (much better) you allocate the space you need for the
strings with MemPtrNew() and change the type of the strings to char*
without const. Another way would be to declare the structure with
character arrays instead of character pointers, like char name[32]. But
then you have to be careful not to overwrite this buffer.
