#pragma bcd
(3) unsigned int adbcdbe (x, y) ;
unsigned char x ;
unsigned char y ;
Decimal addition is carried out by the BCD adjustment instruction (with result expansion).
(4) unsigned int sbbcdbe (x, y) ;
unsigned char x ;
unsigned char y ;

Decimal addition is carried out by the BCD adjustment instruction.
(6) unsigned int sbbcdw (x, y) ;
unsigned int x ;
unsigned int y ;
Decimal subtraction is carried out by the BCD adjustment instruction.
(7) unsigned long adbcdwe (x, y) ;
unsigned int x ;
unsigned int y ;
Decimal addition is carried out by the BCD adjustment instruction (with result expansion).
(8) unsigned long sbbcdwe (x, y) ;
unsigned int x ;
unsigned int y ;
Decimal subtraction is carried out by the BCD adjustment instruction (with result expansion). If a borrow occurs,
