Your first problem is that the char * fields (I'd agree with Richard that
they should be declared const) only point to the location of, for instance,
the 8 digit number which defines the SrvCall. Where do you plan on that
location being?
A more usual simple approach is
typedef struct
{
SDWord FormID; // a number id
char SrvCall[10]; // 8 digit number (with NULL terminator and
padding)
char OpenDate[16]; // the date when the form opened/created
This actually allocates a certain number of bytes within the record to
stoare each value. You can then declare const char * variables to refer to
these if necessary. This is a reasonably complex subject in it's own right
and I'm just skimming the surface.
I've just guessed about the char [16] for date - the actual space needed
depends on what you're storing. I've also changed the name of the field
because, in general, 'date' is as bad a name for a field as 'number'. Most
naming guidelines suggest that you don't use the type of a field to name
it - 'date' is the type of the data, a useful name identifies what date is
being stored.
