[GNU-COBOL] PIC -> edit masks -> a standard large numeric representation

["David L. Nicol" <david@kasey.umkc.edu>]

"Edit masks"

Sounds like a reasonable standard internal representation for
numeric data would be a 64 bit integer and a 8-bit edit mask
with bits in it set for the various switches.

The "edit mask generator" would parse PIC into edit masks.

#include <sys/types.h>
typedef struct _NumericAtom{
	unsigned short editmask;
	int_64_t numdata;
} NumericAtom;


Records could then be stored as arrays of these 10-byte things, 

A COBOL to C converter could associate the name of the field
with the offset into the array structure.


and the C compiler would worry about efficiency issues.

A-type data could overrun several NumericAtoms
