Perhaps this may be naive, but shouldn't the above be converted into a
structure ?

struct elem_G
{
  unsigned char X[2];
  unsigned char Y[2];
};

static struct elem_G f_G;

Also, Pascal has types called records and strings (not null terminated C
type strings).

Since these types are similar to COBOL types, maybe it could be used as a
model. 

PS: 
Structures may have boundary aliment problems on certain architectures,
such as i386.
