I know Euphoria does not have structures that is why I would like to know
what would be the equivalent of this in Euphoria Style.
typedef struct {
unsigned int no;
char n[4][32];
char tel[16],fax[16];
} IDNAME;

What I mean is will it occupy the same amount of Disk Space. In memory I
dont realy care, but on Disk it matters since a whole data base is created
using the Structure of 162Bytes.
